Question

Find all the numbers such that the sum of twice the number and 8 is greater than or equal to tour times the number​

Answer 1

Explanation:

Let the number = x

2x + 8 ≥ 4x Subtract 2x from both sides.

8 ≥ 4x - 2x Combine

8 ≥ 2x Divide by 2

8/2 ≥ 2x/2 Combine

4 ≥ x

What this means is that the largest value the x can have is 4. Any number greater that 4 will make the use of ≥ incorrect.
