    3. The first equation can be multiplied by 3 and the second equation by 2.

    Step-by-step explanation:

    2 x + 3 y = 25 (1)

    -3 x + 4 y = 22 (2)

    Multiply equation (1) by 3 and (2) by 2.

    3 (2x) = 6x

    2 (-3x) = - 6x

    When you add the two equations, x will get cancelled last
