You bought some new fish and need the tank ready. You fill the tank with water and start running the filter system. You check the temperature of the water after 2 hours and notice the water is 78 degrees Fahrenheit. You need the temperature to be at 72 degrees Fahrenheit. after three additional hours and the water temperature is at so, you add the fish. What was the temperature when you first filled the tank?

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

36 girls
