    From the second equation it follows that y = b - x. Substitute this into the first equation:

    2x + 3(b - x) = a.

    Now expand and solve for x.

    Once you have x, substitute it into y = b - x and solve for y.

    Hello,

    From the second equation, we have : x=b-y

    Then if we replace it in the first one, we get :

    2(b-y)+3y=a

    2b-2y+3y=a

    y=a-2b

    Hence x=b-(a-2b)=-a+3b
