Well first, you have to get both equations to the y= form
y=mx+b

X=-5-y   add y to x

y+x=-5   then subtract x

y=-x-5     is your equation
_____________________

for the second one:

2+y=-x+3    subtract 2

y=-x+1         is your equation
__________________________
Take both equations and compare:

Both the slopes are the same of -x, so that means the will lines never touch (also because of different y intercept)

So, the answer is parallel.

We want to solve
3e^{2x}+5=27

Subtract 5 from each side.
3e^{2x}=22
Divide each side by 3.
e^{2x}=7.3333
Take natural logs of each side.
2x=ln(7.3333)=1.9924
Divide each side by 2.
x = 0.9962

Answer:  x = 0.996  (nearest thousanth)
