    Can you explain and show me how to work this problem?

  • math help please -

    x = 65 - 2y

    2x + 3y = 105

    Substitute 65-2y for x in second equation and solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.

    It definitely is not D! You are right with B.
