3(1)^2-3= 0
Plug in the numbers because x=1 plug In 3(1)^2 and it equals 3 then subtract y which is 3-3= 0
The correct answer would be -5 > q
In order to solve this using only addition and subtraction, what we need to do is change the side each term is on. This will allow us to get the variable to be a positive number.
-q > 5 ----> Subtract 5 from both sides
-5 - q > 0 -----> Add q to both sides
-5 > q
