12x+3=3x+3
Combine 2x and x to get 3x.
12x+3-3x=3
Subtract 3x from both sides.
9x+3=3
Combine 12x and -3x to get 9x.
9x=3-3
Subtract 3 from both sides.
9x=0
Subtract 3 from 3 to get 0.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since 9 is not equal to 0, x must be equal to 0.
