Answer:

Option : ( 2 , 6 )

x = 2, y = 6

Explanation:


y = 4x - 2 ---------------- ( 1 )


y = -2x + 10 -------------- ( 2 )

Substitution Method

Substitute ( 1 ) in ( 2 ) :


4x - 2 = -2x + 10\\\\4x + 2x = 10 + 2\\\\6x = 12\\\\x = 2

Now substitute x in ( 2 ):


y = -2x + 10\\\\y = -2 ( 2 ) + 10\\\\y = - 4 + 10 \\\\y = 6
