x+0x+x+0x-6=3
Multiply 0 and 6 to get 0. Multiply 0 and 6 to get 0.
x+0+x+0x-6=3
Anything times zero gives zero.
2x+0+0x-6=3
Combine x and x to get 2x.
2x+0+0-6=3
Anything times zero gives zero.
2x-6=3
Add 0 and 0 to get 0.
2x=3+6
Add 6 to both sides.
2x=9
Add 3 and 6 to get 9.
x=\frac{9}{2}
Divide both sides by 2.
