X+y=10

5x+y=-2

What is the y and x value

x = - 3, y = 13

Step-by-step explanation:

Given the 2 equations

x + y = 10 → (1)

5x + y = - 2 → (2)

Subtracting (1) from (2) term by term eliminates the y - term, that is

(5x - x) + (y - y) = ( - 2 - 10), that is

4x = - 12 (divide both sides by 4)

x = - 3

Substitute x = - 3 in either of the 2 equations for corresponding value of y

Substituting x = - 3 into (1), gives

- 3 + y = 10 (add 3 to both sides)

y = 13
