Solve equation X X 6 16 with three different methods

If it helps, be cautious, Xie Di Xiao Chong Xie sentenced to annihilation.

x=x-1+6 5x 1 6 This is a one-dimensional equation of limb Jingdou, and the specific draft is as follows:

x=x-1+6/5x×1/6

Solve the equation: x=x-1+1 5x (combine similar terms below) x-x-1 5x=-1

1/5x=-1

1/5x=1

1/5x×5/1=1×5/1

x=5/1x=5

Solution: x=x-1+6 5x*1 6

x=x-1+x width difference type leather 5

x-x-x/5=-1

x/5=-1x=5

Please see the answer to the diagram of the Dumb Eggplant Concealment Fiber Tape Hall:

According to the suspicion of the liquid buried imitation of the inscription can be obtained:

x=x-1+6x Qinshan 5*1 6

x-x=-1+x/5

0=-1+x/5

x/5=1x=5

Move the term to obtain: 6x+2x=16, merge the same kind of term: 8x=16, and the coefficient is 1 to obtain: x=2

Summary. Pro-understanding x=16-6x=10

16-x=6 to solve the equation.

Pro-understanding x=16-6x=10

Pro, such an equation, we can understand it according to the usual subtraction formula, this is the relationship between the subtracted number and the subtraction equal to the difference.

So one of the subtractions is equal to the subtraction of the difference.

Solution x=30 5x=6

This is the multiplication relationship.

Thank you, teacher.

You're welcome, thank you for your consultation, I hope this service can help you, you can click on my avatar to follow me, and if you have any questions in the future, please consult me again, and finally wish you a happy life!

This topic is the calculation of a one-dimensional equation, and the detailed process is as follows;

16x two 12 (x 6), 4x two 3 (x 6), 4x 3x 18, 4x 3x two 18, x 18.

The calculation process for this problem is as follows:

Left = 16x = 16 * 18 = 288, right = 12 (x 6) 12 (18 6) and state 12 24 two 288, left = right, i.e. x = 18 is the solution of the equation.

Knowledge expansion: A univariate equation is an equation that contains only one unknown, the highest number of unknowns is 1, and both sides are integers. There is only one root of the unary equation, and the unary equation can solve most of the engineering problems, travel problems, distribution problems, profit and loss problems, integral table problems, billing problems, and number problems.

x^2-6x-16=0

x+2)(x-8)=0

x+2=0 or x-8=0
