Isolate the X in the second equation
x=2y+14
Substitute that in for the x in the fist equation
7(2y+14) + 2y = 2
Distribute the 7
14y+14+2y=2
Combine like terms
16y+14=2
Isolate the 16y
16y=-12
Isolate y by dividing the whole equation by 16
y=-12/16
Simplify
y=-3/4
That is your y. To find x, plug y into one of the equations. I'm plugging it into the version of the second equation after we isolated x.
x=2(-3/4)+14
Distribute the 2
x=(-1.5)+14
Simplify
x=12.5
Since the number before the number in the tenth place (7) is greater than 5 (8), you will be rounding up. So your answer is 9.80

To find FDH and FDE you first need to solve GDH.
Here’s how to set up GDH.
8x-1=6x+15
Subtract 6x from both sides so that it cancels out.
2x-1=15
Add 1 to both sides so that it cancels out.
2x=16
Divide by 2z
x=8
Plug in.
GDH: 8(8)-1+6(8)+15=78
FDH: 122+78= 200
FDE: 122+15=137
