How do you solve and graph #2n4<=22# or #8n5>=53#?
1 Answer
See a step process below;
Explanation:
Adding
Divide both sides by
Similarly..
Adding
Divide both sides by
So we have;
Therefore;
or
Note that there are no values which are a solution for BOTH inequalities....
That is the reason for the use of the word 'or' rather than 'and'.
On a number line graph you would have the following:
Two separate parts of the graph:

A line with a closed (full) circle on
#9# and extending to the left to negative infinity. 
A line with a closed (full) circle on
#6# and extending to the right to positive infinity.
A value from either of these will be a possible solution for one of the inequalities given.
Can someone help me to plot these two graphs??
