Answer:
(- 3, 5 )
Step-by-step explanation:
Given the 2 equations
x + y = 2 → (1)
5x + y = - 10 → (2)
Subtracting (1) from (2) term by term will eliminate the term in y, that is
(5x - x) + (y - y) = (- 10 - 2)
4x = - 12 ( divide both sides by 4 )
x = - 3
Substitute x = - 3 into either of the 2 equations and solve for y
Substituting into (1)
- 3 + y = 2 ( add 3 to both sides )
y = 5
Solution is (- 3, 5 )
