    Answer:

    x = 5

    Step-by-step explanation:

    Subtract 7 from both sides:  3x + 7- 7 = 22 – 7

    Simplify: 3x = 15

    Divide both sides by 3

    Simplify: x = 5

    Hope this helps:)

    Answer:

    x=5

    Step-by-step explanation:

    Given 3x+7=22, our goal is to isolate x such that will have an equation that tell us x is equal to something.

    Start by subtracting 7 from both sides:

    3x+7-7=22-7,\\3x=15

    Divide both sides by 3:

    \frac{3x}{3}=\frac{15}{3},\\x=\frac{15}{3}=\boxed{5}

    Therefore, the value of x=5 makes the equation 3x+7=22 true.
