Answer:
(- 2, 7)
Step-by-step explanation:
Given the 2 equations
4x + y = - 1 → (1)
y = - 2x + 3 → (2)
Substitute y = - 2x + 3 into (1)
4x - 2x + 3 = - 1
2x + 3 = - 1 ( subtract 3 from both sides )
2x = - 4 ( divide both sides by 2 (
x = - 2
Substitute x = - 2 into (2) for corresponding value of y
y = -2(- 2) + 3 = 4 + 3 = 7
Solution is (- 2, 7)
