Answer:
x>3 is the answer
Explanation:
We are given one inequality
7x-9>2x+6
To solve this we can do additions and subtraction as we do for equations.
Only for multiplication if negative number is used inequality changes
So let us add 9 to both the sides
7x>2x+6+9
Now subtract 2x from both the sides
7x-2x >15
5x>15
We divide by a positive number 5 without disturbing inequality sign.
X>3 is the answer
In interval notation we can write this as open interval
(3,∞)
In number line this is the region to the right of 3, not includig 3
