324=36\times 6+12x
Multiply 4 and 9 to get 36. Multiply 2 and 6 to get 12.
324=216+12x
Multiply 36 and 6 to get 216.
216+12x=324
Swap sides so that all variable terms are on the left hand side.
12x=324-216
Subtract 216 from both sides.
12x=108
Subtract 216 from 324 to get 108.
x=\frac{108}{12}
Divide both sides by 12.
x=9
Divide 108 by 12 to get 9.
