Question

1) x + 2y = 9 & 2x - y = 8​

Answer 1

Answer:

x = 5, y = 2

Step-by-step explanation:

x + 2y = 9 ---- (1)

2x - y = 8 ----(2)

Multiplying (1) by 2

= 2x + 4y = 18 ----(3)

Subtracting (2) from (3) we get

2x - 2x + 4y + y = 18 - 8

5y = 10

y = 2 ----(4)

substituting (4) in (1)

x + 4 = 9

x = 5
