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

5x + 1 = 7x - 3
5x = 7x - 4
-2x = -4
x = 2

JK = 5(2) + 1 = 11
JL = 2 * JK = 2 * 11 = 22
