Answer:

x = [tex]\frac{9}{4}[/tex]

Step-by-step explanation:

7 = [tex]\frac{1}{3}[/tex](8x + 3)

  • we want to isolate x on one side of this equation, so first get rid of the [tex]\frac{1}{3}[/tex] by multiplying 3 onto both sides of the equation. Your resultant should be:

21 = 8x + 3

  • Now subtract 3 from both sides. This will make division easier

18 = 8x

  • divide both sides by 8. This will isolate x on the right side of the equation.

[tex]\frac{18}{8}[/tex] = [tex]\frac{9}{4}[/tex] = x
