Question

2x- y=2 and 4x- y=4​

Answer 1

Answer:

x = 1

Explanation:

• 2x - y = 2
• 4x - y = 4

• 2x - 4x = 2 - 4

• -2x = -2

• x = 1

Answer 2

Answer:

2x-y=2 then 2x=2+y

X=2+y/2 eq¹ put this eqn in 4x-y=4

4(2+y/2)-y=4

8+4y/2-y=4

8+4y-2y/2=4

8+2y=4×2

2y=8-8

y=0

put value of y in eq 1

Explanation:

x=2+0/2

value of X is 1
