Answer:  [tex]\textsf{x = 2}[/tex]

-------------------------------------------------------------------------------------------------------------

Given:  [tex]\textsf{3x + 1 = 7}[/tex]

Find:  [tex]\textsf{Solve for x}[/tex]

Solution: In order to isolate x we need to subtract 1 from both sides and the divide both sides by 3.

Subtract 1 from both sides

  • [tex]\textsf{3x + 1 - 1 = 7 - 1}[/tex]
  • [tex]\textsf{3x = 7 - 1}[/tex]
  • [tex]\textsf{3x = 6}[/tex]

Divide both sides by 3

  • [tex]\textsf{3x/3 = 6/3}[/tex]
  • [tex]\textsf{x = 6/3}[/tex]
  • [tex]\textsf{x = 2}[/tex]

Therefore, the value of x is equal to 2.
