Answer:
No Solution
Step-by-step explanation:
For system of equations, you must equal the equations to each other like shown below:
![3x + 1 = 3x + 7](https://tex.z-dn.net/?f=3x%20%2B%201%20%3D%203x%20%2B%207)
Solve for x by subtracting 3x from both sides of the equation:
≠ ![7](https://tex.z-dn.net/?f=7)
Direct Variation<span>. Directly Proportional. A relationship between two variables in which one is a constant multiple of the other. In particular, when one variable changes the other changes in proportion to the first. If b is directly proportional to a, the equation is of the form b = ka (where k is a constant).</span>

Answer:
x = 5 pens
y = 7 pencils
Step-by-step explanation:
let
x = the number of pens
y = the number of pencils
Anthony spent $2.80 to buy a total of 12 pens and pencils
0.35x + 0.15y = 2.80
x + y = 12
by solving the system of equations
0.35x + 0.15y = 2.80
x + y = 12
we find
x = 5 pens
y = 7 pencils
