<h3><u>
The value of x is greater than the value of 3.</u></h3>
We can treat inequalities like standard algebraic equations.
7x - 9 > 2x + 6
<em><u>Add 9 to both sides.</u></em>
7x > 2x + 15
<em><u>Subtract 2x from both sides.</u></em>
5x > 15
<em><u>Divide both sides by 5.</u></em>
x > 3
Answer:
25%
Step-by-step explanation:

Required
Which of a to d has no solution
(a)
and 
We have: 
Sole for m



Divide by 6

So, we have:
and 
implies that: m = -6,-7,-8,-9.....
implies that m = -3,-2,-1,0.....
<em>Hence, there is no solution</em>
