To eliminate all of the fractions in an equation, we can multiply the equation by the least common denominator of all of the fractions in the equation. To find the LCD, we need to find a number that has at least all of the factors of each of the denominators.
To find the LCD of the fractions in this equation, let's look at our denominators, 3 and 6. We can say 3 = 3 and 6 = 2 * 3. By examining this, we can see that our LCD has to have a 3 and 2, since those numbers are found in at least one of the fractions. Thus, our LCD is 3 * 2 = 6.
Now we know to multiply our entire equation by 6. This is solved as shown:
Our answer is 4x + 42 = 5.

We first have to change the mixed number into a fraction and we do this by multiplying the denominator to the whole number and adding the product to the numerator.
It looks something like this:
4×1=4 (Multiply the denominator and the whole number)
4+3=7 (Add the product and the numerator)
Keep the same denominator
Now that we have the improper fraction, we can subtract.
Now in order to subtract we have to have a common denominator, so lets make both of the denominators 20.
21÷20=1.05 or

1x3=3+4=7
7/4-7/10
now make a common denominator
the common denominator is 20 so do 4x5=20 and 10x2=20
do the same to the numerators 7x5=35 and 7x2=14
35/20-14/20
the answer as an improper fraction is 21/20 and as a mixed number it is 1 1/20
