Question

10у-7х=-10 10+х=2 найти переменную х;у

Answer 1

10y-7x=-10
-7x+10y=-10
7x-10y=10



10+x=2
X=-2-10
X=-8

Answer 2

To solve the system of equations, we'll first find the value of variable x and then use it to find the value of variable y.

Given system of equations:

1. 10y - 7x = -10
2. 10 + x = 2

Step 1: Solve for variable x in equation (2): 10 + x = 2 Subtract 10 from both sides to isolate x: x = 2 - 10 x = -8

Step 2: Substitute the value of x into equation (1) to solve for variable y: 10y - 7x = -10 10y - 7(-8) = -10 10y + 56 = -10 Subtract 56 from both sides to isolate y: 10y = -10 - 56 10y = -66 Divide by 10 to find y: y = -66 / 10 y = -6.6

The solution to the system of equations is x = -8 and y = -6.6.
