\sf{\huge{\underline{\pink{Answer :-}}}}

2x+y-6=0

4x-2y-4 = 0

Making equation perfect,

2x + y = 6 -------(1) × 2

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

4x + 2y = 12 -------(3)

Subtracting (3) by (2) ,

4x + 2y = 12 -------(3)

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

________________

8x = 16

________________

➝ x = 16/8

x = 2

Putting in (2) ,

4x - 2y = 4

➝ 4 × 2 - 2y = 4

➝ 8 - 2y = 4

➝ - 2y = 4 - 8

➝ - 2y = - 4

➝ y = - 4 / -2

y = 2

\sf{\huge{\underline{\green{Answer :-}}}}

4x - 2y = 4

➝ 4 × 2 - 2 × 2 = 4

➝ 8 - 4 = 4

4 = 4
