Answer:
(- 10, 13 )
Step-by-step explanation:
Given the 2 equations
- 3x + 2y = 56 → (1)
- 5x - 2y = 24 → (2)
Adding the 2 equations term by term eliminates the y- term, that is
- 8x = 80 ( divide both sides by - 8 )
x = - 10
Substitute x = - 10 into either of the 2 equations and solve for y
Substituting into (1)
- 3(- 10) + 2y = 56
30 + 2y = 56 ( subtract 30 from both sides )
2y = 26 ( divide both sides by 2 )
y = 13
Solution is (- 10, 13 )
