Here is a group of maths questions get them right you get a prize... got to show working out... for example

2y+3x=13 ----> 4y+6x=26
7y-2x=8 ----> 21y-6x=24
----------------------
29x+0y=183
Y=2

2y+3x=13
2x2+3x=13
4+3x=13
x=3

You have to do setting out like this so i can check the answers and give away rewards... Goood Luck

Question 1)

6x-5y=-7
3x+4y=16

2) 3y-4x=1
6y-6x=5

3)
4x+3y=4
2x-5y=15
