Answer:
(- 2, 5 )
Step-by-step explanation:
Given the 2 equations
y = - 4x - 3 → (1)
y = - 2x + 1 → (2)
Since both equations express y in terms of x, equate the right sides, that is
- 4x - 3 = - 2x + 1 ( add 2x to both sides )
- 2x - 3 = 1 ( add 3 to both sides )
- 2x = 4 ( divide both sides by - 2 )
x = - 2
Substitute x = - 2 into either of the 2 equations for corresponding value of y
Substituting x = - 2 in (2), then
y = - 2(- 2) + 1 = 4 + 1 = 5
Solution is (- 2, 5 )
