WebOct 10, 2024 · Solve the second equation for x by adding y to both sides: (x - y) + y = 1 + y. So x = 1 + y. Take that value of x, and substitute it into the first equation given above (x + y = 3). With that substitution the first equation becomes (1+y) + y = 3. That means 1 + 2y = 3. Subtract 1 from each side: 2y = 2. So y = 1. WebSolve the simultaneous equations: \ (2x + y = 9\) (1) \ (3x - y = 1\) (2) Add the two equations together and you will find that the \ (y\) disappears: \ (3x + 2x + y - y = 9 + 1\) This can...
