1. solve for x and y
2x-y=1
2x+2y=10

(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 )
