12a-4\geq 144
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
12a\geq 144+4
Add 4 to both sides.
12a\geq 148
Add 144 and 4 to get 148.
a\geq \frac{148}{12}
Divide both sides by 12. Since 12 is positive, the inequality direction remains the same.
a\geq \frac{37}{3}
Reduce the fraction \frac{148}{12} to lowest terms by extracting and canceling out 4.
