    c = 3 c = - 1/2

    Step-by-step explanation:

    (4c-5) ^2 = 49

    Take the square root of each side

    sqrt ((4c-5) ^2) = ±qrt (49)

    4c-5 = ±7

    Separate into two equations

    4c-5 = 7 4c-5 = - 7

    Add 5 to each side

    4c-5+5 = 7+5 4c-5+5 = -7+5

    4c = 12 4c = - 2

    Divide by 4

    4c/4 = 12/4 4c/4 = - 2/4

    c = 3 c = - 1/2
