Solve 2x+9 greater or equal to 5 and 2x-13greater or equal to 9 what is the solution? I have x=-2 and x=2 how do I write this {x x> what?

Answer 1

2x + 9 ≥ 5
2x = -4
x = -2

2x-13 ≥ 9
2x ≥ 22
x ≥ 11

Answer 2

Or, to actually answer the question,

x ≥ -2 and x ≥ 11

Since any x ≥ 11 is also x ≥ -2, the only solution is x ≥ -2.

{x:x ≥ -2}

Answer 3
