Question

the difference of y and 3 is greater than or equal to -18

"difference" means subtraction

the "difference of y and 3" would be y-3

"greater than or equal to" is the inequality symbol ≥

is "greater than or equal to -18" would be ≥-18

y-3 ≥ -18

Answer 2

y-3>= -18

or 3-y >= -18

y>=-15 or y<=21
