Answer:
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
