    a, b, and c are our 3 integers. Can you make equations using a, b, and c using what you were given in your question?

    A + B + C = 92

    C= (A-10) * 2

    Now substitue the 2 last equations into the first one :)

    A + (A(3)) + ((A - 10)(2)) = 92

    i think the equation for c is close, but not correct

    c = 2a - 10 i think

    but yeah after you fix that and plug it in, you just solve for A

    Yes, c = 2a -10 is correct. Solve for a, then you can solve for b and c by using the last 2 equations.
