Question

y=2x-2 y=4x-4 by alimination method​

Answer 1

y = 2x - 2

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

y = 4x - 4

4x - y = 4 ----(2)

From 1 and 2,

(2) - (1)

4x - y = 4

-[2x - y = 2]

–––––––––

2x = 2

x = 1

Put x = 1 in any equation,

2x - y = 2

2(1) - y = 2

2 - y = 2

y = 0

Hope it helps..!

Answer 2

heya

ANSWER:

2x-y=2---- multiples with 2
