Answer:
(- 4, 9 )
Step-by-step explanation:
Given the 2 equations
3x + 4y = 24 → (1)
3x + 2y = 6 → (2)
Subtract (2) from (1) term by term to eliminate x
3x - 3x + (4y - 2y) = 24 - 6
2y = 18 ( divide both sides by 2 )
y = 9
Substitute y = 9 into either of the 2 equations and solve for x
Substituting into (1)
3x + 4(9) = 24
3x + 36 = 24 ( subtract 36 from both sides )
3x = - 12 ( divide both sides by 3 )
x = - 4
solution is (- 4, 9 )
