❖ A number y increased by 5 is at least -21.
❖ First, if you come across the word "increased" it means we
"increase" a number, or add something to that number, like
y increased by 5
Now, we are also given that this expression is at least -21, which means it can't be -21; it can be -21 or it can be greater than -21.
So we have
Solving for y
- Subtract 5 on both sides:-
So the values of y greater than or equal to -26 will make this inequality true.
Good luck with your studies.
