Write an equation or inequality to represent the scenario:
aniked [119]
<h3><u>The value of x is equal to 1.</u></h3><h3><u>6(x + 2) = 20x - 2</u></h3>

<em><u>Distributive property.</u></em>

6x + 12 = 20x - 2

<em><u>Add 2 to both sides.</u></em>

6x + 14 = 20x

<em><u>Subtract 16x from both sides.</u></em>

14 = 14x

<em><u>Divide both sides by x.</u></em>

x = 1
