Answer:
(- 4, - 5 )
Explanation:
Given the 2 equations
2x - y = - 3 → (1)
3x + 4y = - 32 → (2)
Multiplying (1) by 4 and adding to (2) will eliminate the term in y
8x - 4y = - 12 → (3)
Add (2) and (3) term by term to eliminate y
11x = - 44 ( divide both sides by 11 )
x = - 4
Substitute x = - 4 into either of the 2 equations for corresponding value of y
Substituting in (2) gives
3(- 4) + 4y = - 32
- 12 + 4y = - 32 ( add 12 to both sides )
4y = - 20 ( divide both sides by 4 )
y = - 5
Solution is (- 4, - 5 )
