8x + 12y = 56
9x - 12y = 12-----ADD
17x = 68
x = 4
8 + 3y = 14
3y = 6
y = 2
x = 4 , y = 2

2x+3y= 14
3x-4y= 4
6x+9y=42
6x-8y=8
so 17y=34
y=2
3x= 4+4y with y=2
3x=12
x=4
y=2 x=4
a check can be performed on the other of the two simultaneous equations 2x+3y= 14
8+6=14

2x+3y=14 ------> x3
3x-4y =4 ------> x2
6x+9y=42 minus
6x-8y=8
-----------------------
9y-(-8y) =34
17y =34
y =2
2x+3y = 14
2x + 3(2)=14
2x +6 =14
2x = 14-6
2x = 8
x = 4
x=4
y=2
