x=7x = 7

Step-by-step solution

2 steps

  1. Add 5 to both sides of the equation

    To isolate the term with xx, add 5 to both sides of the equation:
    3x−5+5=16+53x - 5 + 5 = 16 + 5
    3x=213x = 21

  2. Divide by 3

    To solve for xx, divide both sides of the equation by 3:
    3x3=213\frac{3x}{3} = \frac{21}{3}
    x=7x = 7
