    Answer:

    x is equal to 3/2

    Step-by-step explanation:

    Let’s solve it!

    5(4x – 10) + 10x = 4(2x – 3) + 2(x – 4)

    expand:

    20x – 50 + 10x = 8x – 12 + 2x – 8

    group like terms:

    30x – 50 = 10x – 20

    factor out common multiples:

    3x – 5 = x – 2

    group terms again:

    3x – x = -2 + 5

    2x = 3

    and divide both sides by two:

    x = 3/2
