Well just substitute y (the first equation) into the second equation.
So
5x-4(5-3x)=-3
Then just solve the equation from there.
5x-20+12x=-3
17x=17
x=1
and if you need y, y=2

Degger [83]

Answer:

\frac{470}{32-n}  

Step-by-step explanation:  

We have been given that there were 32 volunteers to donate blood. Unfortunately, n of the volunteers did not meet the health requirements, so they couldn't donate.            

So the number of volunteers that donated blood will be 32-n.

We are also told that the rest of the volunteers donated 470 milliliters each.

To find the units of blood donated by each of the volunteers we will divide total units of donated blood by number of volunteers, who donated the blood (32-n).

\text{Millimeters of blood donated by each volunteer}=\frac{470}{32-n}  

Therefore, each of the volunteers donated \frac{470}{32-n} millimeters of blood.
