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

    Distribute the -2 and 3 to expand the respective brackets, then collect like terms, and it becomes a case of simple manipulation to finish. Please show how much you can do.

    Edit: I assume you are trying to show that both sides are equal. Otherwise, there's nothing you can really do here.

    Expand brackets, then group like terms, what do you get?

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

    5q - 2q - 6 = 3q - 6

    3q - 6 = 3q - 6

    3q - 3q = 6 - 6

    0 = 0

    3q - 3q = 6 - 6

    0 = 0

    There is no solution in terms of this equation. Both sides of the equation cancel out.
    Actually there are infinitely many solutions to this equation, because ANY value for q will satisfy the equation.
