Answer:

x = 16

Step-by-step explanation:

5 = 1/2(x) - 3

Add 3 to both sides.

8 = 1/2(x)

Rewrite for clarity.

1/2(x) = 8

x/2 = 8

Multiply both sides by 2.

x = 16.

Proof:

5 = 1/2(x) - 3

Substitute variable.

5 = 1/2(16) - 3

Multiply 1/2 and 16.

5 = 8 - 3

Subtract 3 from 8.

5 = 5

[tex] = > \frac{1}{2} x - 3 = 5[/tex]

[tex] = > \frac{1}{2}x = 5 + 3[/tex]

[tex] = > \frac{1}{2}x = 8[/tex]

[tex] = > x = 8 \times \frac{1}{2} [/tex]

[tex] = > x = 16[/tex]
