i don't comprehend each and every of the TDs, yet different than for MikeG, each and every physique made this way too complicated (x + a million)^2 - 9 = 0 (x + a million)^2 = 9 x + a million = sqrt(9) x + a million = -3 , 3 x = -a million - 3 , -a million + 3 x = -4 , 2 There you flow.

Verified answer
{x ϵ R : x + 2 ≥ -3/11} becomes {x ϵ R : x ≥ -25/11}
I can't find a nice double backed R to use, so this will have to do.
