Answer:
(1, 5 )
Step-by-step explanation:
Given the 2 equations
2x + 4y = 22 → (1)
2x - 2y = - 8 → (2)
Subtract (1) from (2) term by term to eliminate x
2x - 2x - 2y - 4y = - 8 - 22, that is
- 6y = - 30 ( divide both sides by - 6 )
y = 5
Substitute y = 5 in either (1) or (2) and solve for x
Substituting in (1)
2x + 4(5) = 22
2x + 20 = 22 ( subtract 20 from both sides )
2x = 2 ( divide both sides by 2 )
x = 1
Solution is (1, 5 )
