(<em>q = quarters, n = nickles</em>)
<u>First, create your system of equations:</u>
25q + 5n = 535 cents
n = 2q - 5
<u>Second, Substitute for n:</u>
25q + 5(2q - 5) = 535
<u>Simplify:</u>
25q + 10q - 25 = 535
<u>Simplify to solve for q:</u>
35q=560
q=16
<u>Next, solve for n by plugging the value of q back into the equation:</u>
n=2q - 5
n=32-5
n=27
There would be 16 quarters and 27 nickles.

Answer:
y=-11/2-1/2x
Step-by-step explanation:
2x + 4y = -22
4y = -22 - 2x
y=-11/2-1/2x
The slope is -2/3 and the y-intercept is 2. It should look something like this. Let me know if you need more of an explanation.
