Answer:

x = -7

Step-by-step explanation:

Given equation:

[tex]-42 = -7 + 5x[/tex]

  1. Simplify the equation.

        [tex]-42 = 5x -7[/tex]

    2. Flip the equation.

        [tex]5x + 7 = -42[/tex]

    3. Add 7 to each side.

        [tex]5x - 7 + 7 = -42 + 7[/tex]

        [tex]5x = -35[/tex]

    4. Divide both sides by 5.

        [tex]\frac{5x}{5}[/tex] = [tex]\frac{-35}{5}[/tex]

    5. Divide the fraction.

        [tex]-35[/tex] ÷ [tex]5[/tex] = [tex]-7[/tex]
