Question

2x+5 greater than or equal to -1

Answer 1

Solving an inequality

For inequalities separate variables and numerical terms

So then variables goes to left, and terms to right

2x + 5 ≥ -1

2x ≥ -1 -5

2x ≥ -6

and then

x≥ -6/2= -3

Is a plane formed by all numbers equal or bigger than -3
