Answer:
(- 1, - 3 )
Step-by-step explanation:
Given the 2 equations
2x + y = - 5 → (1)
2x - 5y = 13 → (2)
Subtracting (1) from (2) term by term will eliminate the x-0 term
0 - 5y - y = 13 - (- 5) , that is
- 6y = 18 ( divide both sides by - 6 )
y = - 3
Substitute y = - 3 into either of the 2 equations and solve for x
Substituting into (1)
2x - 3 = - 5 ( add 3 to both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1
solution is (- 1, - 3 )
