4x+23=-21-3x-26
Combine x and 3x to get 4x.
4x+23=-47-3x
Subtract 26 from -21 to get -47.
4x+23+3x=-47
Add 3x to both sides.
7x+23=-47
Combine 4x and 3x to get 7x.
7x=-47-23
Subtract 23 from both sides.
7x=-70
Subtract 23 from -47 to get -70.
x=\frac{-70}{7}
Divide both sides by 7.
x=-10
Divide -70 by 7 to get -10.
