1. Problem Description

The problem is to solve the linear equation 72x=57 - 2x = -5 for the variable xx.

2. Solution Steps

We need to isolate xx on one side of the equation.
First, subtract 7 from both sides of the equation:
72x7=577 - 2x - 7 = -5 - 7
2x=12-2x = -12
Next, divide both sides by -2:
2x2=122\frac{-2x}{-2} = \frac{-12}{-2}
x=6x = 6

3. Final Answer

The solution to the equation 72x=57 - 2x = -5 is x=6x = 6.
