    Answer:

    x = – 11/4

    Step-by-step explanation:

    20- 3x = 9 – 7x

    Add 7x to both sides

    20 – 3x + 7x  =  9 – 7x + 7x

    20 + 4x = 9    

    Now,Subtract 20 from both sides

    20 -20 + 4x = 9 – 20

                 4x = -11        {Divide both sides b 4}

                   x = -11/4

    Answer:

    = -11/4

    Step-by-step explanation:

    Rearrange terms

    −3+20=9−7

    − 3 + 20 = − 7 + 9

    Subtract  20  from both sides of the equation

    − 3 + 20 = − 7 + 9

    − 3 + 20 − 20 = − 7 + 9 − 20

    Simplify / Subtract the numbers

    − 3 = − 7 − 1 1

    Add  7 7x 7x  to both sides of the equation

    − 3 = − 7 − 1 1

    − 3 + 7 = − 7 − 1 1 + 7

    Simplify / Combine like terms

    4 = − 1 1

    Divide both sides of the equation by the same term

    4 = −11

    4/4 = -11/4

    Simplify / Cancel terms that are in both the numerator and denominator

    = -11/4
