-5x-21=9x+45
Use the distributive property to multiply 9 by x+5.
-5x-21-9x=45
Subtract 9x from both sides.
-14x-21=45
Combine -5x and -9x to get -14x.
-14x=45+21
Add 21 to both sides.
-14x=66
Add 45 and 21 to get 66.
x=\frac{66}{-14}
Divide both sides by -14.
x=-\frac{33}{7}
Reduce the fraction \frac{66}{-14} to lowest terms by extracting and canceling out 2.
