Question

Given the figure below, find the values of x and z.
(8x – 20)
(14x – 20)

Answer 1

Problem #1: x = 2.5

Problem #2: x = 10/7

Explanation:

Step 1: Find the value of x in (8x - 20)

8x - 20 = 0

Add 20 to both sides

8x - 20 + 20 = 0 + 20

8x = 20

Divide both sides by 8

8x / 8 = 20 / 8

x = 2.5

Answer: x = 2.5

Step 2: Find the value of x in (14x - 20)

14x - 20 = 0

Add 20 to both sides

14x - 20 + 20 = 0 + 20

14x = 20

Divide both sides by 14

14x / 14 = 20 / 14

x = 10/7

Answer: x = 10/7
