24=x+12
Variable x cannot be equal to -12 since division by zero is not defined. Multiply both sides of the equation by 24\left(x+12\right), the least common multiple of 4\times 3+x,24.
x+12=24
Swap sides so that all variable terms are on the left hand side.
x=24-12
Subtract 12 from both sides.
x=12
Subtract 12 from 24 to get 12.
