When you add any fractions, you need to find a common denominator. In this case they have no common factors so you just multiply them together. First multiply the first fraction by
which gets you
. Then multiply the second fraction by
to get
. Now you can add them together to get
.
(b)
now you can pull out root 2 and get
which equals
The answer to that question is
<u>47/50 </u>
-3x = 81.
Let's divide left and right by -3 to isolate x.
