Answer:

The answer is: the nursing student received a $2,100 loan and the business student received a $2,900 loan

Explanation:

                 n = nursing student               b = business student

step 1:

n + b = 5,000

5%n + 7%b = 308

step 2: we multiply (5%n + 7%b = 308) x -20

n + b = 5,000

-n - 1.4b = -6,160

step 3: we subtract

(n - n) + (b - 1.4b) = 5,000 - 6,160

-0.4b = -1,160

step 4: we divide

-0.4b / -0.4 = -1,160 / -0.4

b = 2,900

step 5: we replace

n + 2,900 = 5,000

n = 2,100
