    You can using any equation you want to solve for one of the variables. For instance,  if you want to solve for x you turn one of the equations so y is by its self

    2x + 3y = 5
     4x – y =3

    I am going to use 4x – y =3
    -y = -4x + 3
    y = 4x -3
    Now you can substitute 4x – 3 for y  in 2x + 3y = 5 and solve for x
    2x + 3y = 5
    2x + 3(4x – 3) = 5
