What is the solution to the sentence: "A number decreased by -5 is at least 7"?

so a number degreased by -5 means a number +5 so x-(-5) is at least 7 x+5 > 7
so subtract 5 from both sides x > 2
the solution is any number more than, and including, 2

n-5=7
add 5 to both sides
n=12

The solution to the sentence "A number decreased by -5 is at least 7" is that the number must be greater than or equal to 2. This means x ≥ 2 . Any number that is 2 or greater will satisfy the original condition.
