    Simplifying

    x + -5(x + 2) = x + 3(3 + -2x)

    Reorder the terms:

    x + -5(2 + x) = x + 3(3 + -2x)

    x + (2 * -5 + x * -5) = x + 3(3 + -2x)

    x + (-10 + -5x) = x + 3(3 + -2x)

    Reorder the terms:

    -10 + x + -5x = x + 3(3 + -2x)

    Combine like terms: x + -5x = -4x

    -10 + -4x = x + 3(3 + -2x)

    -10 + -4x = x + (3 * 3 + -2x * 3)

    -10 + -4x = x + (9 + -6x)

    Reorder the terms:

    -10 + -4x = 9 + x + -6x

    Combine like terms: x + -6x = -5x

    -10 + -4x = 9 + -5x

    Solving

    -10 + -4x = 9 + -5x

    Solving for variable 'x'.

    Move all terms containing x to the left, all other terms to the right.

    Add '5x' to each side of the equation.

    -10 + -4x + 5x = 9 + -5x + 5x

    Combine like terms: -4x + 5x = 1x

    -10 + 1x = 9 + -5x + 5x

    Combine like terms: -5x + 5x = 0

    -10 + 1x = 9 + 0

    -10 + 1x = 9

    Add '10' to each side of the equation.

    -10 + 10 + 1x = 9 + 10

    Combine like terms: -10 + 10 = 0

    0 + 1x = 9 + 10

    1x = 9 + 10

    Combine like terms: 9 + 10 = 19

    1x = 19

    Divide each side by '1'.

    x = 19

    Simplifying

    x = 19

    Hope this helps. Good Luck!!!!

    x-5(x+2)=x+3(3-2x)

    x - 5x - 10= x+9-6x order of operations multiplication comes first which is why I distrubited the 5 first.

    -4x-10=-5x +9

    x=19 positive 19

    x - 5(x + 2) = x + 3(3 - 2x)

    x-5x -10=x+9-6x

    -4x-10=-5x+9

    -10=-x+9

    -19=-x

    19=x

    i got 19 instead of -19

    you were close though :D

    the answer is +19

    x-5(x+2)=x+3(3-2x)

    x-5x-10=x+9-6x

    -4x-10=-5x+9

    5x-4x=9+10

    x=19

    x-5(x+2)=x+3(3-2x)

    x-5x+(-10)=x+9+(-6)

    do inverse operation

    6=(-10)+-4

    x-5x+(-4)=x+9

    do inverse again

    4+9=13

    x-5x=x+13

    and so on
