\frac{3}{2}x+\frac{12}{4}+\frac{3}{4}=\frac{1}{4}x
Convert 3 to fraction \frac{12}{4}.
\frac{3}{2}x+\frac{12+3}{4}=\frac{1}{4}x
Since \frac{12}{4} and \frac{3}{4} have the same denominator, add them by adding their numerators.
\frac{3}{2}x+\frac{15}{4}=\frac{1}{4}x
Add 12 and 3 to get 15.
\frac{3}{2}x+\frac{15}{4}-\frac{1}{4}x=0
Subtract \frac{1}{4}x from both sides.
\frac{5}{4}x+\frac{15}{4}=0
Combine \frac{3}{2}x and -\frac{1}{4}x to get \frac{5}{4}x.
\frac{5}{4}x=-\frac{15}{4}
Subtract \frac{15}{4} from both sides. Anything subtracted from zero gives its negation.
x=-\frac{15}{4}\times \frac{4}{5}
Multiply both sides by \frac{4}{5}, the reciprocal of \frac{5}{4}.
x=\frac{-15\times 4}{4\times 5}
Multiply -\frac{15}{4} times \frac{4}{5} by multiplying numerator times numerator and denominator times denominator.
x=\frac{-15}{5}
Cancel out 4 in both numerator and denominator.
x=-3
Divide -15 by 5 to get -3.
