sum= addition
times= multiplication
at least= ≥
"At least" means the left side of the equation cannot be any less than 11. The left side will be at least/at minimum 11.
2x + 1 ≥ 11
subtract 1 from both sides
2x ≥ 10
divide both sides by 2
x ≥ 5
ANSWER: x ≥ 5; x is greater than or equal to (or "at least") 5
Hope this helps! :)
