Answer:
The solution is: [tex]x = 9[/tex]
Explanation:
Question
[tex]\frac{x-1}{2} = 4[/tex]
Required
Solve the equation
[tex]\frac{x-1}{2} = 4[/tex]
Multiply through by 2
[tex]2 * \frac{x-1}{2} = 4 * 2[/tex]
[tex]x - 1 = 4 * 2[/tex]
[tex]x - 1 = 8[/tex]
Add 1 to both sides
[tex]x - 1 + 1 = 8 + 1[/tex]
[tex]x = 8 + 1[/tex]
[tex]x = 9[/tex]
