5\times 2+30=8w
Multiply both sides of the equation by 40, the least common multiple of 8,4,5.
10+30=8w
Multiply 5 and 2 to get 10.
40=8w
Add 10 and 30 to get 40.
8w=40
Swap sides so that all variable terms are on the left hand side.
w=\frac{40}{8}
Divide both sides by 8.
w=5
Divide 40 by 8 to get 5.
