7\left(x+8\right)=3\left(x-3\right)-63
Multiply both sides of the equation by 21, the least common multiple of 3,7.
7x+56=3\left(x-3\right)-63
Use the distributive property to multiply 7 by x+8.
7x+56=3x-9-63
Use the distributive property to multiply 3 by x-3.
7x+56=3x-72
Subtract 63 from -9 to get -72.
7x+56-3x=-72
Subtract 3x from both sides.
4x+56=-72
Combine 7x and -3x to get 4x.
4x=-72-56
Subtract 56 from both sides.
4x=-128
Subtract 56 from -72 to get -128.
x=\frac{-128}{4}
Divide both sides by 4.
x=-32
Divide -128 by 4 to get -32.
