Question

Solve 2x – y = 6, x – y = 2.

Answer 1

Answer:

x = 4

y = 2

Step-by-step explanation:

2x – y = 6  ---------(1)

x – y = 2.  ---------(2)

(1) - 2(2)

=> (2x-y) - 2(x-y) = 6 - 2(2)

=> 2x-y - 2x + 2y = 6 - 4

=> -y+ 2y = 2

=> y = 2

substitute y=2 in (2)

(2)=> x-2 = 2

=> x = 2+2

=> x = 4
