How do you solve 3/7n=6?

Jul 12, 2015

I found $n = 14$

Explanation:

Here you want to find the value of $n$.
So, try to "isolate" it on one side (say, the left) taking all the numbers to the other side of the $=$ sign.

To do that you must always balance your equation so that your "balance" is always in equilibrium!

For example: you can take $3$ to the right BUT remember the it was multiplying on the left so you must change into a division to move it to the right:
$\frac{n}{7} = \frac{6}{\textcolor{red}{3}}$
Same thing with $7$; it was divided on the left so it ends up multiplying on the right:
$n = \textcolor{b l u e}{7} \cdot \frac{6}{\textcolor{red}{3}}$
so:
$n = 7 \cdot 2 = 14$

hope it helps!
