Answer:

x = 4, y = 1

Step-by-step explanation:

Given the 2 equations

4x + y = 17 → (1)

2x + y = 9 → (2)

Subtract (1) from (2) term by term

(4x - 2x) + (y - y) = (17 - 9)

2x = 8 ( divide both sides by 2 )

x = 4

Substitute x = 4 into (1) and solve for y

4(4) + y = 17

16 + y = 17 ( subtract 16 from both sides )

y = 1
