Answer: x = 0
Step-by-step explanation:
4x − 3 + x = 7x − 3
Step 1: Simplify both sides of the equation.
4x − 3 + x = 7x − 3
4x + −3 + x = 7x + −3
(4x + x) + (−3) = 7x − 3(Combine Like Terms)
5x + −3 = 7x − 3
5x − 3 = 7x − 3
Step 2: Subtract 7x from both sides.
5x − 3 − 7x = 7x − 3 − 7x
−2x − 3 = −3
Step 3: Add 3 to both sides.
−2x − 3 + 3 = −3 + 3
−2x = 0
Step 4: Divide both sides by -2.
-2x/-2 = 0/-2
x = 0
If it doubles every 4 hours, in 12 hours you will have 3 doublings.
2 * 2 * 2 = 8
90*8 = 720 pounds of algae
