    First distribute invisble - 1

    -1 (7x+3.5) = - 7x-3.5

    and distribute 3

    3 (x-2.5) = 3x-7.5

    now we have

    10-7x-3.5=-5.75+3x-7.5

    combine

    6.5-7x=-13.25+3x

    add 7x to both sides

    6.5=-13.25+10x

    add 13.25 to both sides

    19.75=10x

    divide both sides by 10

    1.975=x
