Answer: b-4 ≥ 16 || Solved: b≥ 20
Explanation:
The keywords in this math problem: The DIFFERENCE between b and 4, and this shows subtraction. So, b - 4. AT LEAST means greater than or equal to.
Now we have the equation b-4 ≥ 16.
To solve this, we add 4 to both sides of the equation- 4+4 cancels out, and 16+4 = 20.
That leaves the variable alone and the final answer is b ≥ 20.
Hope this helps!
