    problem one: w = 10 or B

    Problem two: x = 96 or A

    Step-by-step explanation:

    Problem One

    I take it these are two different questions.

    15 + 3w = 45 Subtract 15 from both sides

    15 - 15 + 3w = 45 - 15 Combine like terms

    3w = 30 Divide by 3

    3w/3 = 30/3 Do the division

    w = 10

    Problem 2

    Switch Sides

    x/6 - 1 = 15 Add 1 to both sides

    x/6 - 1 + 1 = 15 + 1 Combine like terms

    x/6 = 16 Multiply both sides by 6

    x/6 * 6 = 16 * 6 Combine

    x = 96
