Answer: Option C is correct.
<h3><u>Part A</u></h3>
⇒ 4x = 20
⇒ x = 20/4
⇒ x = 5
<h3><u>Part B</u></h3>
⇒ x/2 = 8
⇒ x = 8(2)
⇒ x = 16
<h3><u>Part C</u></h3>
⇒ x + 8 = 3x
⇒ 3x - x = 8
⇒ 2x = 8
⇒ x = 4
<h3><u>Part D</u></h3>
⇒ x = (x + 5)/2
⇒ 2x = x + 5
⇒ 2x - x = 5
⇒ x = 5

21/2
Step-by-step explanation:
(x-8)/5=2/4
step 1 you simplify if you can to make it easier
(x-8)/5=1/2
step 2 multiply each side by 5
x-8=5/2
step 3 add each side by 8
x=5/2+8
16/2+5/2=21/2
x=21/2
The answer is -5 i hope this helps!!
