just substract the two fractions by taking the greatest common divisor of 335 and 5300. Then you are left with a linear equation.
then you can just multiply both sides by 5 to get 3-2=5x
It's the same as combining the fractions to get
You can either combine the fractions or just multiply both sides by the denominators.
is another way.
If x=5, then 2x=10 by multiplying both sides by 2, they are still equal and saying the same thing.
5=5, 5(2)=5(2), (3+2)=5, 2(3+2)=2(5)
If two sides are the same, then if you multiply all terms of both sides
by the same number, they will still be equal.
You should get used to adding fractions, so that it becomes easy,
however, multiplying by the denominators in this case is faster.
Note : you are not actually doing anything to the equation by multiplying by 335 inside the fraction : you are only rewriting a fraction in a different form (but it is equivalent) to make it simpler to add. Therefore, since the equation is left unchanged, doing anything to the other side would be superfluous. Simple example :
See ? It is basically equivalent to multiplying the fraction by 1, but adding multiplicative information to allow fraction addition. Since multiplying by 1 does not change anything, there is nothing to change on the other side of the equation
