The another way to represent the same line, for solving will be:
<u><em>Explanation</em></u>
Given equation of the line is:
"Solving " means <u>we need to get</u>
<u>alone in left side.</u> So, we will eliminate all other terms except
from the left side.
First we will <u>subtract 2x </u>from both sides. So, we will get......
Now, we will <u>divide both sides by 3</u> for getting alone. So.....
Thus, the another way to represent the same line, for solving will be:
We have been given the expression
We can rewrite the expression as
In order to simplify the given expression, we can check if we have any common terms in the numerator and denominator.
We can write the term 72 which is in the numerator as
Thus, the expression becomes
We can see that 4 is common in both numerator and denominator. Hence, we can cancel 4. Thus, we are left with
Therefore, we can rewrite the given expression as 54.
