x+56=3\left(16+x\right)
Variable x cannot be equal to -56 since division by zero is not defined. Multiply both sides of the equation by 3\left(x+56\right), the least common multiple of 3,56+x.
x+56=48+3x
Use the distributive property to multiply 3 by 16+x.
x+56-3x=48
Subtract 3x from both sides.
-2x+56=48
Combine x and -3x to get -2x.
-2x=48-56
Subtract 56 from both sides.
-2x=-8
Subtract 56 from 48 to get -8.
x=\frac{-8}{-2}
Divide both sides by -2.
x=4
Divide -8 by -2 to get 4.
