    C (x=3)

    Step-by-step explanation:

    4 (5x+3) = 14x+30

    1) Use the Distributive property on the left side of the equation:

    20x+12=14x+30

    2) Subtract a 12 from both sides:

    20x=14x+18

    3) Subtract a 14x from both sides:

    6x=18

    4) Divide both sides by 6:

    x=18/6

    5) Simplify the fraction 18/6:

    x=3
