Step-by-step explanation:
Answer:
(44, - 27 )
Step-by-step explanation:
Given the 2 equations
5x + 8y = 4 → (1)
2x + 3y = 7 → (2)
Multiplying (1) by 2 and (2) by - 5 , then adding the result will eliminate x
10x + 16y = 8 → (3)
- 10x - 15y = - 35 → (4)
Add (3) and (4) term by term to eliminate x
y = - 27
Substitute y = - 27 into either of the 2 equations and solve for x
Substituting into (2)
2x + 3(- 27) = 7
2x - 81 = 7 ( add 81 to both sides )
2x = 88 ( divide both sides by 2 )
x = 44
solution is (44, - 27 )
