\frac{3}{4}x\geq 12+3
Add 3 to both sides.
\frac{3}{4}x\geq 15
Add 12 and 3 to get 15.
x\geq 15\times \frac{4}{3}
Multiply both sides by \frac{4}{3}, the reciprocal of \frac{3}{4}. Since \frac{3}{4} is positive, the inequality direction remains the same.
x\geq \frac{15\times 4}{3}
Express 15\times \frac{4}{3} as a single fraction.
x\geq \frac{60}{3}
Multiply 15 and 4 to get 60.
x\geq 20
Divide 60 by 3 to get 20.
