-3x-5y=61 (1) 7x-5y=-9 (2) Looking at the equations, we can multiply either of them by -1 to cancel the y's. Let's do that to the 2nd one. -3x-5y=61 -7x+5y=9 Then add the equations together. -10x=70 x=-7 Plug that back into either original equation to solve for y.

A much easier way to do this would be: 1) x+y=1300 2) x+2z=1400 3) x+y+z=1600 Look at 1 and 2. Since x+y=1300 and x+y+z=1600, z obviously equals 300. Now substitute that back in #2. x+2(300)=1400, x+600=1400, x=800. Now substitute x and z back in #3. x+y+z=1600, 800+y+300=1600...
