Answer:
(6, 5 )
Step-by-step explanation:
Given the 2 equations
4x + 8y = 64 → (1)
7x - 2y = 32 → (2)
Multiplying (2) by 4 and adding to (1) will eliminate the y- term
28x - 8y = 128 → (3)
Add (1) and (3) term by term, that is
32x = 192 ( divide both sides by 32 )
x = 6
Substitute x = 6 into either of the 2 equations
Substituting x = 6 into (1)
4(6) + 8y = 64, that is
24 + 8y = 64 ( subtract 24 from both sides )
8y = 40 ( divide both sides by 8 )
y = 5
Solution is (6, 5 )
