    Answer:

    x = 4

    Step-by-step explanation:

    • -2x + 38 = 2(3 + 3x)

    Use distributive property to multiply 2 by 3 and 3x

    • -2x + 38 = 2 ×3 + 2 × 3x
    • -2x + 38 = 6 + 6x

    subtract 6x from both side

    • -2x + 38 – 6x = 6 + 6x – 6x

    combine -2x and -6x to get -8x

    • -8x + 38 = 6

    subtract 38 from both side

    • -8x + 38 – 38 = 6 – 38

    subtract 38 from 6 to get -32

    • -8x = -32

    divide both side by -8

     \small \sf \frac{-8x}{ -8} =  \frac{-32}{-8} \\ \\   \small \sf x =  \frac{- 32}{-8}

    divide -32 by -8 to get 4

    • x = 4

    Answer:

    Step-by-step explanation:

    -2x +38 = 2(3 + 3x)

    -2x + 38 = 2*3 + 2*3x

    -2x + 38 = 6 + 6x

    Add 2x to both sides

    38 = 6 + 6x + 2x  

    Combine like terms

    38 = 6 + 8x

    Subtract 8  from both sides

    38 – 6 = 8x

    8x = 32

    Divide both sides by 8

    x = 32/8

    x = 4
