    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
