No, because all the sides have to be equal
<span>6x + 10y = 32 (mult. eq by 2)
6x + 2y = 22
subtract:
8y = 10
y = 1 0/8 = 1.25
x = 16 - 5y = 9.75
cost/lb of walnuts = $1.25
cost/lb of chocolate chips = $9.75</span>

Writing some equations out might help!
1) You know that a is 4/5 of b. This can be written as:

.
To find what b is equal to, multiply both sides by 5/4:

.
A is 5/4 B.
2) You know that a is 1/5 smaller than b. This can be written as:

.
To find b, just add 1/5 to both sides:

.
B is 1/5 bigger than a.
