12=4\times 4+12x\times \frac{1}{4}
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 12x, the least common multiple of x,3x,4.
12=16+12x\times \frac{1}{4}
Multiply 4 and 4 to get 16.
12=16+3x
Multiply 12 and \frac{1}{4} to get 3.
16+3x=12
Swap sides so that all variable terms are on the left hand side.
3x=12-16
Subtract 16 from both sides.
3x=-4
Subtract 16 from 12 to get -4.
x=\frac{-4}{3}
Divide both sides by 3.
x=-\frac{4}{3}
Fraction \frac{-4}{3} can be rewritten as -\frac{4}{3} by extracting the negative sign.
