    x = 1/3

    Step-by-step explanation:

    8x - 3 (5x-2) = 7-10x

    Distribute

    8x - 15x + 6 = 7-10x

    Combine like terms

    -7x + 6 = 7 - 10x

    Add 10x to each side

    -7x + 10x + 6 = 7 - 10x+10x

    3x+6 = 7

    Subtract 6 from each side

    3x+6-6 = 7-6

    3x = 1

    Divide each side by 3

    3x/3 = 1/3

    x = 1/3

    Answer: x = 1/3

    Step-by-step explanation: Start by changing the - 3 to plus a negative 3 so you know that you are distributing a - 3 through the parentheses.

    -3 (5x) is - 15x and - 3 (-2) is 6.

    So we have 8x - 15x + 6 = 7 - 10x.

    Simplifying the left side further gives us - 7x + 6 = 7 - 10x.

    Now subtract 6 from both sides to get - 7x = 1 - 10x.

    Now add 10x to both sides to get 3x = 1.

    From here it should be easy to find that x = 1/3.
