PLEASE HELP!!


Elizabeth creates the following system of equations to determine how many apples, a, and oranges, r, she should buy when she goes to the farmer’s market.

3a + 3r = 6
a − r = 4

Elizabeth determines that the solution (a, r) to the system of equations that she created is (3, −1). Is her solution correct? In context, is her solution viable?

Select one:
A. Yes, her solution is correct; yes, her solution is viable in context.
B. Yes, her solution is correct; no, her solution is not viable in context.
C. No, her solution is incorrect; yes, her solution is viable in context.
D. No, her solution is incorrect; no, her solution is not viable in context.

Answer:

A.

Step-by-step explanation:

3a+3r=6

a-r=4

+r. +r

a=4+r

3(4+r)+3r=6

12+3r+3r=6

6r=-6

r=-1
