Using simultaneous equations find x & y. Equation A: 3x + 2y = 3 -y and Equation B: 5x + 3y = 6 + x

So firstly, it makes it a lot easier if we put all the stuff we don't know on one side, and the numbers on the other. Be careful moving the -y over to the other side. This would give Equation A as 3x + 3y = 3 and Equation B as 4x + 3y = 6 . As you can see in both equations we have a +3y. An easy thing to help with these type of questions is remembering SSS (same signs subtract)- I can show you how this works if you want, or if you think it will complicate it we can stick with remembering SSS. 4x + 3y = 6- 3x + 3y = 3= x = 3If we then substitute that back in to one of the original equations (always pick the easiest one- here equation B looks better as there are no minus signs which could lead to a silly mistake. (5*3) + 3y = (6+3)15 + 3y = 93y = 9-153y = -6y=-2
x = 3 and y = -2 At the end clearly write your 2 answers (just to be sure the examiner can clearly see you are a maths genius!)
