Answer:
(- 9, 6 )
Explanation:
Given the 2 equations
3x - 2y = - 39 → (1)
5x + 2y = - 33 → (2)
Adding the 2 equations, term by term, will eliminate the y- term, that is
8x = - 72 ( divide both sides by 8 )
x = - 9
Substitute x = - 9 in either of the 2 equations and solve for y
Substituting into (2)
5(- 9) + 2y = - 33
- 45 + 2y = - 33 ( add 45 to both sides )
2y = 12 ( divide both sides by 2 )
y = 6
Solution is (- 9, 6 )
