    Solve

    2.5x-13=2

    Add 13 to both sides

    2.5x=15

    Divide 2.5 on both sides

    Final Answer: x = 6

    Check

    2.5x-13=2

    Substitue 6 for x

    2.5 (6) - 13=2

    Multiply 2.5 by 6

    15-13=2

    Add 13 to both sides

    Final Answer: 15=15 This proves that the x value (6) is true
