Answer:
x=-4.992 and x=-0.434
Step-by-step explanation:
we have

we can divide the equation above into two equations
so
----> equation A
----> equation B
Solve by graphing
The solutions of the system are the x-coordinates of the intersection points both graphs
using a graphing tool
The solutions are x=-4.992 and x=-0.434
see the attached figure

To help with thinking about this, we can say that the 6 gallons of 50% acid contains 3 gallons of pure acid and 3 gallons of filler. This would make the concentration 3/6, or 50%. Adding a gallon of pure acid would shift the concentration to 4/7, or 57.1%.
When the relationship becomes 70%, four gallons of pure acid have been added.
3+4 7
—— = — = 70%
6+4 10
