Answer:
(- 6, - 16 )
Step-by-step explanation:
Given the 2 equations
- 4x + y = 8 → (1)
2x - y = 4 → (2)
Adding the 2 equations term by term will eliminate the term in y
- 2x = 12 ( divide both sides by - 2 )
x = - 6
Substitute x = - 6 into either of the 2 equations and soilve for y
Substituting x = - 6 into (2)
2(- 6) - y = 4
- 12 - y = 4 ( add 12 to both sides )
- y = 16 ( multiply both sides by - 1 )
y = - 16
Solution is (- 6, - 16 )
