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
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
