Answer:
1. 2x+2-(2x-14)=5x+2
0x+16=5x+2
16=5x+2
14=5x
14/5=x or 2.8=x
2. 2x+10-(-2x+7)=-7x+14
4x+3=-7x+14
11x+3=14
11x=11
x=1
Step-by-step explanation:

Answer:
0.25
Step-by-step explanation:
Suppose that a large mixing tank initially holds 300 gallons of water is which 50 pounds of salt have been dissolved. Another brine solution is pumped into the tank at a rate of 3 gal/min, and when the solution is well stirred, it is then pumped out at a slower rate of 2 gal/min. If the concentration of the solution entering is 2 lb/gal, determine a differential equation for the amount of salt A(t) in the tank at time t.
