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]
