4x is greater than or equal to 20

subtract 4 from each side and then you are left with x is greater than or equal to 16

Since it's 4x (not 4+x) you need to divide by 4, not subtract 4:

4x >= 20
x >= 5

To solve the inequality 4x ≥ 20, we follow these steps:

1. Divide both sides of the inequality by 4 to isolate the variable x: (4x)/4 ≥ 20/4
This simplifies to: x ≥ 5

Therefore, the solution to the inequality 4x ≥ 20 is x ≥ 5.
