216-9\left(x+2\right)=144x+968
Multiply both sides of the equation by 72, the least common multiple of 8,9.
216-9x-18=144x+968
Use the distributive property to multiply -9 by 1x+2.
198-9x=144x+968
Subtract 18 from 216 to get 198.
198-9x-144x=968
Subtract 144x from both sides.
198-153x=968
Combine -9x and -144x to get -153x.
-153x=968-198
Subtract 198 from both sides.
-153x=770
Subtract 198 from 968 to get 770.
x=\frac{770}{-153}
Divide both sides by -153.
x=-\frac{770}{153}
Fraction \frac{770}{-153} can be rewritten as -\frac{770}{153} by extracting the negative sign.
