Answer:

[tex] \large \boxed{x = 4}[/tex]

Step-by-step explanation:

Goal

  • Solve for x-term.

Given

  • Equation

[tex]7x - 2 = 26[/tex]

Step 1

  • Isolate x by adding 2 to both sides.

[tex]7x - 2 + 2 = 26 + 2 \\ 7x + 0 = 28 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4[/tex]

Step 2 (Optional)

  • We check the answer by substituting x = 4 in the equation.

[tex]7x - 2 = 26 \\ 7(4) - 2 = 26 \\ 28 - 2 = 26 \\ 26 = 26[/tex]

The equation is true for x = 4. Hence, the solution is x = 4.
