    x = - 5.33333333

    Step-by-step explanation:

    Using dist. prop

    3x - 6 + 4x = 10x + 10

    combine like terms

    7x - 6 = 10x + 10

    move the 6 over

    7x = 10x + 16

    move the 10x over

    -3x = 16

    divide by - 3

    x = - 5.33333333

    -16/3

    Step-by-step explanation:

    3 (x-2) + 4x = 10 (x+1)

    Expand brackets

    3x - 6 + 4x = 10x+10

    Collect like terms;

    3x+4x - 6 = 10x+10

    7x-6 = 10x+10

    Collect like terms;

    7x-10x = 10+6

    -3x = 166

    X = - 16/3 = - 5 1/3
