If −18≥6−12ax -18\geq6-12ax −18≥6−12ax minus, 18, is greater than or equal to, 6, minus, 12, a, x , which inequality represents the possible range of values of 1−2ax1-2ax 1−2ax

First we observe that we have the following inequality:
 -18≥6-12ax
 We take common factor from the right side:
 -18≥6 (1-2ax)
 Then, we clear:
 -18 / 6≥ (1-2ax)
 -3≥ (1-2ax)
 
 An inequality that represents the possible range of values 1-2ax is:
 -3≥ (1-2ax)
