    For h(x) = -7x + 10, x =1

    For r(x) = 4/5x+ 7 , x = -15

    Step-by-step explanation:

    in order to find the value of x on which the functions will have given values, we will put the functions equal to the given values

    So,

    h(x) = -7x + 10; h(x) = 3

    h(x) = -7x+10\\3 = -7x+10\\3-10 = -7x+10-10\\-7 = -7x

    Dividing both sides by -7

    \frac{-7x}{-7} = \frac{-7}{-7}\\x = 1

    r(x) =  4/5x+7; r(x) = -5

    r(x) = \frac{4}{5}x +7\\-5 = \frac{4}{5}x +7\\-5-7 = \frac{4}{5}x\\-12 = \frac{4}{5}x\\x = -12 * \frac{5}{4}\\x = -15
