72x=288+x\left(-7\right)
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
72x-x\left(-7\right)=288
Subtract x\left(-7\right) from both sides.
79x=288
Combine 72x and -x\left(-7\right) to get 79x.
x=\frac{288}{79}
Divide both sides by 79.
