40+45+50+40+x=45\times 5
Multiply both sides by 5.
85+50+40+x=45\times 5
Add 40 and 45 to get 85.
135+40+x=45\times 5
Add 85 and 50 to get 135.
175+x=45\times 5
Add 135 and 40 to get 175.
175+x=225
Multiply 45 and 5 to get 225.
x=225-175
Subtract 175 from both sides.
x=50
Subtract 175 from 225 to get 50.
