Solve
7x¡Ý21
I think it is
{x©¦x>or equal to 3}
To solve the inequality 7x ≥ 21, you need to isolate the variable x. Here's how you can do it step by step:
1. Divide both sides of the inequality by 7. This will give you:
x ≥ 3
So your answer, {x | x ≥ 3}, is correct. It represents the set of all values of x that are greater than or equal to 3, including 3 itself.
