Answer is (n + 3) + (n - 7)
Simplified to 2n - 4
Using “n” for number
Call b the amount of babysitting hours and 5 the amount of gardening hours.
10b+5g=80
b+g=12
Subtract 5 times the second equation from the first to get:
5b=20
Thus, b=4. g=12-4, or 8. Therefore, Sarah spends 4 hours babysitting and the rest gardening.
