x 125 1 5x How do I do this?

Solve the equation: x+125=

Solution: When calculating a one-dimensional equation, first consider moving the term related to the unknown to the left of the equation, and then moving the constant to the right of the equation. If there are coefficients in front of the unknown, multiplication and division will be performed to get the final answer.

Here we can directly merge similar terms, put the unknowns on the left side of the equation, and put the constants on the right side of the equation, and proceed to the next step to calculate and get the answer.

The detailed process of solving the equation is as follows.

x+125=

x=125÷

x=250So, you can get x=250 through the process of solving the equation above: Solution: When we calculate the division operation, try to choose that both the dividend and the divisor are integers.

If there is a decimal between the dividend and the divisor, it can be calculated as an integer. When calculating, you should start from the high position of the dividend, divide the divider in turn, get the quotient, keep the remainder, and then calculate the next step. If it is an infinite loop decimal place, it can be calculated to a few decimal places as required.

Step 1: 12 5 = 2, remaining 2

Step 2: 25 5 = 5

Step 3: On the basis of the answers in the first two steps, multiply by 10 to get 250 So, you can use the division operation of vertical calculation to get the answer is 250.

Column equations. Calculate x+125=

Problem Solving Idea: Calculate a one-dimensional equation.

You need to move the unknown to the left and the constant to the right, and finally calculate the result of the unknown after the move is completed.

Solution: x+125=

x=125÷

x=250 Extended Data: The dividend.

The divisor is performed from each digit from the high position, and the quotient obtained each time is retained, and the remainder is retained.

Add the next digit to the operation, and the divisor will be divided into digits in this order, and the obtained quotient will be combined in order, and the remainder is the result of the last operation.

Problem solving: Step 1: Because the divisor is not an integer, first convert the divisor to an integer of 5, and the dividend is expanded by the same multiple as 1250

Step 2: 12 5=2 The remainder is: 2

Step 3: 25 5=5 The remainder is: 0

Step 4: 0 5=0 The remainder is: 0

According to the above calculation steps, the combined result is 250

x+125＝

250 x for this problem, you can simply combine similar terms and then calculate the result. It's not difficult, it's just that you have to pay attention to the calculation and don't make it wrong.

The problem is an equation that subtracts x from both sides at the same time

Equal to 125, x, equal to 250

The process of solving the equation is as follows.

x+125＝

x＝125÷

Parse: x=125

x = 250: x and so on are not slippery at 250. Prepare a ruler.

x+1x Yu 5+45=125%x

Solution: Vertical filial piety 125%x-6 5x=45

125%x-120x 100=45

x=900

Solution: 5+5x=125;

Subtract 5,5x=120 from both sides of the equation;

x=120/5=24
