Answer:
Step-by-step explanation:
Both the equations that you modelled are correct.
Use the substitution method to solve the system of equations
Take the first equation
Now this becomes our third equation and now insert it into our second equation
Now insert R = 223 in any equation. Lets insert it into equation number three
So 223 number of roll papers were sold and 303 number of candles were sold.
I have attached the graph below check it out.
Where both the equations of line intersect is our solution thus we can confirm that our answer is correct.
Check the picture below.
notice the reflected gray line on the red one over the y=x line, the slope of either line across the y=x line is simply the other's upside-down.
