Answer:
(20, 12 )
Step-by-step explanation:
Given the 2 equations
2x + 3y = 76 → (1)
- 2x + 5y = 20 → (2)
Adding the 2 equations term by term will eliminate the x- term
0 +8y = 96
8y = 96 ( divide both sides by 8 )
y = 12
Substitute y = 12 into either of the 2 equations and solve for x
Substituting into (1)
2x + 3(12) = 76
2x + 36 = 76 ( subtract 36 from both sides )
2x = 40 ( divide both sides by 2 )
x = 20
solution is (20, 12 )
