9x-11=21x+28
Multiply both sides of the equation by 7.
9x-11-21x=28
Subtract 21x from both sides.
-12x-11=28
Combine 9x and -21x to get -12x.
-12x=28+11
Add 11 to both sides.
-12x=39
Add 28 and 11 to get 39.
x=\frac{39}{-12}
Divide both sides by -12.
x=-\frac{13}{4}
Reduce the fraction \frac{39}{-12} to lowest terms by extracting and canceling out 3.
