Answer:
![p+n=0](https://tex.z-dn.net/?f=p%2Bn%3D0)
Step-by-step explanation:
Given that Lincoln has
pennies and
nickles and that his total worth is $0,
we can express his total using the inequality:
![p+n=0](https://tex.z-dn.net/?f=p%2Bn%3D0)
Where the sum of n and p is his total
Hence, Lincoln's situation is expressed as p+n=0
You can use elimination
x - y = 7
0.5x + y = 5
1.5x = 12
x = 8
Then plug in x into one of the original equations
8 - y = 7
y = 1
Solution is (8,1)

its going to be B)18 -5i just took the test
Answer:
Okay!
Step-by-step explanation:
Let's solve for x
5x+2y=3
Step 1: Add -2y to both sides.
Step 2: Divide both sides by 5.
