Answer:
B: x = 8
Step-by-step explanation:
16 = 8 + x
x = 16 - 8
x = 8
<h3><u>
The value of x is equal to 21.</u></h3>
13 = 5 + 2(x - 17)
<em><u>Distributive property.</u></em>
13 = 5 + 2x - 34
<em><u>Add 34 to both sides.</u></em>
47 = 5 + 2x
<em><u>Subtract 5 from both sides.</u></em>
42 = 2x
<em><u>Divide both sides by 2.</u></em>
x = 21
