15w+4=5\left(3\times 3+1\right)
Multiply both sides of the equation by 15, the least common multiple of 15,3.
15w+4=5\left(9+1\right)
Multiply 3 and 3 to get 9.
15w+4=5\times 10
Add 9 and 1 to get 10.
15w+4=50
Multiply 5 and 10 to get 50.
15w=50-4
Subtract 4 from both sides.
15w=46
Subtract 4 from 50 to get 46.
w=\frac{46}{15}
Divide both sides by 15.
