Question

870-x=500 + 700 решите ​

Answer 1

Ответ:

500+700=1200

870-1200=-330

Answer 2

To solve the equation 870 - x = 500 + 700, we can follow these steps:

1. Simplify both sides of the equation by performing the addition and subtraction operations:

870 - x = 500 + 700 870 - x = 1200

2. To isolate the variable x, we need to move the constant term (-x) to the other side of the equation. We can do this by subtracting 870 from both sides:

870 - x - 870 = 1200 - 870 -x = 330

3. To solve for x, we multiply both sides of the equation by -1 to change the sign of x:

(-1) * (-x) = (-1) * 330 x = -330

Therefore, the solution to the equation 870 - x = 500 + 700 is x = -330.
