45\times 2=3x+3
Multiply both sides by 2, the reciprocal of \frac{1}{2}.
90=3x+3
Multiply 45 and 2 to get 90.
3x+3=90
Swap sides so that all variable terms are on the left hand side.
3x=90-3
Subtract 3 from both sides.
3x=87
Subtract 3 from 90 to get 87.
x=\frac{87}{3}
Divide both sides by 3.
x=29
Divide 87 by 3 to get 29.
