Answer:
[tex] \large \boxed{x = 4}[/tex]
Step-by-step explanation:
Goal
Given
[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.
