2 pounds ---- 100%
x pounds -----18%
x=(2*18)/100=36/100=0.36 pounds
To complete the solution of - x - 8y = -1, we first need to substitute x for -15.
As so:
-(-15) - 8y = -1
15 - 8y = -1
Next, we can subtract 15 from each side to get:
15 - 15 - 8y = -1 - 15
- 8y = -16
Now, we can divide by -8 on each side to get the y by itself:
-8y / -8 = -16 / -8
y = -16 / -8
y = 2
There we go! <em>y</em> = 2 when x = -15! Hope I could help you out! Have a good one.

Work Shown:
When going from 234 to 9*26, the idea here is to factor where one factor is the largest perfect square possible. That way we can use the rule 
to break up the root and simplify.
