Final answer:

The mistake in the given solution is in the step where they divide both sides of the equation by 5. The correct answer is x = 7.

Step-by-step explanation:

The mistake in the given solution is in the step where they divide both sides of the equation by 5. However, they made an error in simplifying the left side of the equation.

The correct steps to solve the equation are as follows:

  1. Perform the subtraction on the left side of the equation: 5x = 80 - 45 = 35
  2. Divide both sides of the equation by 5: x = 35/5 = 7

Therefore, the correct answer is x = 7.
