Answer:
(- 3, 1 )
Step-by-step explanation:
Given the 2 equations
2x - 2y = - 8 → (1)
x + 2y = - 1 → (2)
Adding the 2 equations will eliminate the y- term, that is
3x = - 9 ( divide both sides by 3 )
x = - 3
Substitute x = - 3 into either of the 2 equations and evaluate for y
Substituting into (2)
- 3 + 2y = - 1 ( add 3 to both sides )
2y = 2 ( divide both sides by 2 )
y = 1
Solution is (- 3, 1 )
