The first step is to see that you need to get a common denominator for the 2/3 and 3/4 so that you can subtract the 2/3 from both sides.

12 is the smallest common multiple of both fractions.

3 goes into 12 four times so multiply the top and bottom by 4 and 2/3 becomes 8/12 : we just renamed 2/3 in terms of 12 in the denominator.

We then do the same thing for the 3/4. 4 goes into 12 three times so we can rename 3/4 as 9/12

Then we can subtract 8/12 from both sides

y +8/12-8/12= 9/12 -8/12

and y=1/12

check.

1/12 +8/12= 9/12

abc is being used as a factor twice therefore according to the laws of exponents when we are multiplying exponents we add them.  In this case abc times abc would be a^2b^2c^2.  abcxabc each variable is raised to the first power so 1+1 equals 2 and therefore the exponent is equal to 2 and you do this for each variable.
