4\times 5a-24=3a+180
Multiply both sides of the equation by 12, the least common multiple of 3,4.
20a-24=3a+180
Multiply 4 and 5 to get 20.
20a-24-3a=180
Subtract 3a from both sides.
17a-24=180
Combine 20a and -3a to get 17a.
17a=180+24
Add 24 to both sides.
17a=204
Add 180 and 24 to get 204.
a=\frac{204}{17}
Divide both sides by 17.
a=12
Divide 204 by 17 to get 12.
