Answer:
Problem #1: x = 2.5
Problem #2: x = 10/7
Step-by-step explanation:
Step 1: Find the value of x in (8x - 20)
8x - 20 = 0
<u>Add 20 to both sides</u>
8x - 20 + 20 = 0 + 20
<em>8x = 20</em>
<em />
<u>Divide both sides by 8</u>
8x / 8 = 20 / 8
<em>x = 2.5</em>
<em />
Answer: x = 2.5
<em />
Step 2: Find the value of x in (14x - 20)
14x - 20 = 0
<u>Add 20 to both sides</u>
14x - 20 + 20 = 0 + 20
<em>14x = 20</em>
<em />
<u>Divide both sides by 14</u>
14x / 14 = 20 / 14
<em>x = 10/7</em>
<em />
Answer: x = 10/7
