    x = 3/4

    Step-by-step explanation:

    Y=4x+7

    Let y = 10

    10 = 4x+7

    Subtract 7 from each side

    10-7=4x+7-7

    3 = 4x

    Divide each side by 4

    3/4 = 4x/4

    3/4 = x

    Steps to solve:

    y = 4x + 7; y = 10

    ~Substitute

    10 = 4x + 7

    ~Subtract 7 to both sides

    10 - 7 = 4x + 7 - 7

    ~Simplify

    3 = 4x

    ~Divide 4 to both sides

    3/4 = 4x/4

    ~Simplify

    3/4 = x

    Best of Luck!
