3x+\frac{45}{9}+50\times 3=60\left(3+x\right)-5\times 176
Multiply both sides of the equation by 10, the least common multiple of 10,2.
3x+5+50\times 3=60\left(3+x\right)-5\times 176
Divide 45 by 9 to get 5.
3x+5+150=60\left(3+x\right)-5\times 176
Multiply 50 and 3 to get 150.
3x+155=60\left(3+x\right)-5\times 176
Add 5 and 150 to get 155.
3x+155=180+60x-5\times 176
Use the distributive property to multiply 60 by 3+x.
3x+155=180+60x-880
Multiply -5 and 176 to get -880.
3x+155=-700+60x
Subtract 880 from 180 to get -700.
3x+155-60x=-700
Subtract 60x from both sides.
-57x+155=-700
Combine 3x and -60x to get -57x.
-57x=-700-155
Subtract 155 from both sides.
-57x=-855
Subtract 155 from -700 to get -855.
x=\frac{-855}{-57}
Divide both sides by -57.
x=15
Divide -855 by -57 to get 15.
