    Answer:

    x=14/3

    Step-by-step explanation:

    4x-3-x+5=30-3x

    3x+2=30-3x

    3x+3x=30-2

    6x=28

    x=28/6=14/3

    x=14/3

    Answer:

    x = 4x^2 – 25

    Step-by-step explanation:

    x*4x – x*3 = 4xsquare – 3x

    4x^2 – 3x – x + 5 = 3*10-3*x

    4x^2 – 4x +5 = 30-3x

    4x^2 +5 – 30 = -3x + 4x

    4x^2 -25 = x

    there fore , x =  4x^2 – 25
