9x+4\left(61-x\right)=324
Multiply both sides of the equation by 36, the least common multiple of 4,9.
9x+244-4x=324
Use the distributive property to multiply 4 by 61-x.
5x+244=324
Combine 9x and -4x to get 5x.
5x=324-244
Subtract 244 from both sides.
5x=80
Subtract 244 from 324 to get 80.
x=\frac{80}{5}
Divide both sides by 5.
x=16
Divide 80 by 5 to get 16.
