    x=2

    Step-by-step explanation:

    -3 (4-x) + 3x=3 (10-5x)

    (-3) (4) + (-3) (-x) + 3x = (3) (10) + (3) (-5x)

    -12+3x+3x=30+-15x

    (3x+3x) + (-12) = -15x+30

    6x+-12=-15x+30

    6x-12=-15x+30

    6x-12+15x=-15x+30+15x

    21x-12=30

    Step 3: Add 12 to both sides.

    21x-12+12=30+12

    21x=42
