The answer is a =
Step-by-step explanation:
<em>1. Convert the mixed fraction to an improper fraction</em>
To find the numerator, multiply the denominator by the whole number and add the numerator to it.
The denominator remains the same.
So, 2 will be
<em>2. Now the equation is,</em>
a - a = + a
<em>3. Take LCM on both sides. </em>
For the left side, multiply the first fraction by and multiply the second fraction by
a - a =
<em>4. Solve by making a the subject</em>
=
=
=10+8a
= 10 + 8a
a = 2(10 + 8a)
a = 20 + 16a
a-16a = 20
-15a = 20
a =
a =
Therefore, the answer is a =
