Subtract each thing (x, y, and constants  (numbers that aren't variables like 1,2,3....) ) separately. 3x – 4y = 25  3x + 2y = 1  3x  3x 4y  2y = 25  1 0x 6y = 24 SO FAR SO GOOD?

so now I solve it from here? 0x + 6y = 24

yes. and 0x + 6y = 24 is just same as 6y = 24 1) Solve for y. 2) plug in the result for y into any of the ORIGINAL equations 3) Solve for x 4) write the answer as (x,y) where x is the xvalue you get AND y, is the yvalue you get.
