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]
