Hello dear world.....
3x+2y=18...given and y=6x-6 given
Lets find what x is. Looks pretty easy peasy.
Substitute that 'y' for 6x -6
Get....3x + 2(6X-6) =18
Lets expand the brackets......
Get 3x + 12x-12 = 18
Add 12 to both sides........
3x +12x = 30
Combine x's
15x=30
Looks like x is twoooooooo
yeeeha!
