20w+12=5\left(6\times 4+3\right)
Multiply both sides of the equation by 20, the least common multiple of 5,4.
20w+12=5\left(24+3\right)
Multiply 6 and 4 to get 24.
20w+12=5\times 27
Add 24 and 3 to get 27.
20w+12=135
Multiply 5 and 27 to get 135.
20w=135-12
Subtract 12 from both sides.
20w=123
Subtract 12 from 135 to get 123.
w=\frac{123}{20}
Divide both sides by 20.
