Question

Hey! I'v been struggling with this question lately. Can someone just lend me a hand?

Answer 1

So, this problem is asking us to find the value of our variable u. 

How can you do this? By isolating the variable, or having only it on one side of the equals sign. 

Here's the step by step approach. It's just simple algebra and reverse order of operation (which is what you should do whenever you are solving for a variable).

$\frac{u+88}{11} = 17$

Multiply both sides by 11 to get rid of the 11 denominator.
$u + 88 = 187$

Then, subtract both sides by 88 to get u by itself.
$u = 99$

Therefore, u is equal to 99. 

Answer 2

You need to isolate the u (get it alone on one side of the "=").

Start by multiplying both sides of the equation by 11 to clear/cancel the denominator on the left:

$11* \frac{u+88}{11} =17*11$

Now you need to subtract 88 from each side to isolate the u:

$u+88=187 \newline \hspace*{.5em} -88 \enspace -88 \newline u \enspace \enspace \enspace \enspace \enspace = 99$
