Question

How do I solve this?
-2y - 7 > 11

Answer 1

incorrect @camille08

Answer 2

-2y - 7 > 11

Add 7 to both sides

-2y > 11 + 7
-2y > 18

Add 2y to both sides; subtract 18 from both sides:

-18 > 2y

Divide both sides by 2:
-18/2 > y

-9 > y

or

y < -9

y is less than -9, not greater.

@Camille08, there's a rule you perform when dividing inequalities by a negative number. Do you remember it?
