Answer: y = - 40/9
Step-by-step explanation:
3 + 2y / 8 = 1 - y / 5
120 + 10y = 40 - 8y
10y + 8y = 40 - 120
18y = -80
y = -40 /9
The system of equations becomes: s + u = 28 This represent the number of candles sold16s + 10u = 400 This represents the value of the candles sold--------------------- Now all that is left is to solve for s and u.
