How do you solve 55 X two 65 5?

This problem is an addition problem, and the addition of x is an unknown number, so you need to use the number of numbers to subtract the number to be added, and then the difference is x.

The equation is: Then x is.

55+x=

x=This can be answered by solving the equation x=.

Solution: Solve the equation, the solution of this equation is x = 21 2, [i.e. x = 55 + x =

55 + x = （65×10+5）/1055 + x = 655/10

x = 655/10 - 55

x = 655/10 - 550/10

x = 105/10

x = 21/2

x = A: The solution of this equation is x = 21 2, [i.e. x =

Is it said that 55+x= how to solve it?

Phase shifting, putting the unknowns on one side and the unknowns on the other side of the equation, taking care to change the symbol when shifting the phase. So it's x=

Have you learned?

Subtract 55 from both sides of the equation at the same time

x is equal to 65 points 5-55, x is equal to.

The process of solving the equation is as follows.

55+x=x=x=look.

Solve the equation: Shift the term to get x = a 55

Combine to get x=

x+ without parentheses to get x+

Move items and merge items of the same kind to get a positive shot of 3x=

Divide both sides of the equation by 3 at the same time to get a hand x = 125 6

Column equations. Compute.

Problem solving ideas: In the process of solving the equation, it is necessary to carry out the merger and negotiation of the same kind of buried and closed terms, and the unknown terms and constant terms.

They were merged separately, and finally the coefficient of the unknown terms was reduced to 1

Problem solving process: x=x=

Liquid test pants calculation: Extended data: The single digit of the two additions is aligned, and then they are in the same counting unit.

The numbers on are added, and the addition result is 10 to the high position, and the addition of the high level needs to accumulate the result of the low position to 1.

Problem solving: Step 1: Advance 1 to the high position and add the decimal part.

Step 2: 5+4+1=0 Advance 1 to the high position

According to the above calculation steps, the combined calculation result is 10

If you have any doubts, please ask and be satisfied.

This unary equation is very simple, just move the term, move to the right of the equal sign, and subtract it from 10 to find the root of the original equation.

The right side of 10 makes up two zeros, zero minus 2 is not enough to subtract, you have to borrow from the previous zero, but the front zero is not enough to borrow, we have to continue to borrow from the zero in the single digit, or not enough to borrow, we borrow from the 1 in the tenth place, the 0 on the hundredth percentile of the state sail becomes 10, 10 minus 2 to get 8, and the 0 on the tenth, the single digit borrows a bit and then leaves a 9, 9 minus 8 to get 1, 9 minus 5 to get 4, the result is that it is the root of the original equation.

I hope I can help you with your doubts.

Solution: According to the conditions that have happened to be known, the column formula is calculated: x x

Answer: Quietly Kai Nian case:

x+55-x=66 can be reduced to 55=66, and it is obvious that this formula is not true of Sun Qi, no matter what value x takes. So there is no solution to the equation!

x=。Flood kite, the re-ethereal craftsman explores the awakening of the longing for the disaster? , the left wheel of the equation is equal to the 24 on the right side of the equation, which proves that the answer is the correct solution of the equation.
