3\left(x-9\right)=8\left(x+7\right)
Multiply both sides of the equation by 24, the least common multiple of 8,3.
3x-27=8\left(x+7\right)
Use the distributive property to multiply 3 by x-9.
3x-27=8x+56
Use the distributive property to multiply 8 by x+7.
3x-27-8x=56
Subtract 8x from both sides.
-5x-27=56
Combine 3x and -8x to get -5x.
-5x=56+27
Add 27 to both sides.
-5x=83
Add 56 and 27 to get 83.
x=\frac{83}{-5}
Divide both sides by -5.
x=-\frac{83}{5}
Fraction \frac{83}{-5} can be rewritten as -\frac{83}{5} by extracting the negative sign.
