Answer:
$5.25
Step-by-step explanation:
$26.25 divided by 5 is $5.25
Using the linear combination method, we can add 3x+7y=31 and -3x-2y=-1 together, which makes 5y=30.
Just divide both sides by 5, and your answer will be y = 6.
To solve for x, just substitute 6 in y in either equation and solve for x:

In short, the correct answer is B. -3 2/3
