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.

3. 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
