Answer:

x ≥ 1

Explanation:

Solving inequalities are essentially like solving equations where the main focus is getting the variable, x in this case, on one side and a constant on the other using inverse operations.

10x+16 ≥ 6x+20

==> subtract 16 from both sides

10x ≥ 6x + 4

==> subtract 6x from both sides

4x ≥ 4

==> divide both sides by 4

x ≥ 1

So the answer would be A

Also an important note for future references is when you divide one of the sides by a negative number you must flip the inequality sign.

E.g. -4x>8

We would divide both sides by -4 and because we divide by a negative number we must flip the inequality signs

This would result to x<-2
