4a/3-b/4=6<br> 5a/6+b=13<br> Solve linear system by elimination

kondor19780726 [428]

$\bf \cfrac{4a}{3}-\cfrac{b}{4}=6
\qquad \qquad 
\cfrac{5a}{6}+b=13
\\\\\\
\textit{let us remove the denominators off those folks}\\
\textit{by multiplying the first one by 12, both sides}\\
\textit{and the second one by 6, both sides, thus}
\\\\\\
12\left( \cfrac{4a}{3}-\cfrac{b}{4} \right)=12(6)\implies 16a-4b=72
\\\\\\
6\left( \cfrac{5a}{6}+b \right)=6(13)\implies 5a+6b=78$

$\bf \textit{now, let's do the elimination}
\\\\

\begin{array}{llll}
16a-4b=72&\boxed{\times 3}\implies &48a-\underline{12b}=216\\\\
5a+6b=78&\boxed{\times 2}\implies &10a+\underline{12b}=156\\
&&--------\\
&&58a+0\quad=372
\end{array}$

solve for "a", once you get "a", plug it back into either equation to get "b"

Assume the average cost of maintaining a dog is the same from month to month. After 55 months, the dog had cost you a total of $

Marizza181 [45]

Answer:

Originally, you will <em>pay</em> $95.75 for the dog.

Step-by-step explanation:

Given:

Maintenance cost of dog after 55 months = $5,468.50

Maintenance cost of dog after 82 months = $8,053.75

To Find:

How much did you pay for the dog originally = ?

Solution:

It is stated that the maintenance cost is same from month to month

Now 82 - 55 = 27 months

For 27 we have paid

$8,053.75 - $5,468.50

$2585.25

But one month the amount paid will be

$\frac{2585.25}{27}$
