Answer:
(2, 3 )
Step-by-step explanation:
Given the 2 equations
2x - y = 1 → (1)
2x + 2y = 10 → (2)
Subtract (2) from (1) term by term to eliminate x
2x - 2x - y - 2y = 1 - 10, that is
- 3y = - 9 ( divide both sides by - 3 )
y = 3
Substitute y = 3 into either (1) or (2) for corresponding value of x
Substituting in (2)
2x + 2(3) = 10
2x + 6 = 10 ( subtract 6 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
Solution is (2, 3 )
