So solving equations is based on the properties of equality.
The denominator is using the property 2 of the equation.
Multiplying or dividing both sides of an equation by a number that is not 0 is still an equation.
For example, (x-2)/3=(2x-4)/2.
If you want to remove the denominator on the left, you must multiply it by three (if you want to multiply it by three, you can remove the denominator), but at this time you should also multiply it by three on the right to keep the balance between the two sides, but the denominator can be removed by multiplying it by two.
So the first step is to remove the denominator at the same time, and both sides must be multiplied at the same time.
Least common multiple of denominator, for example, denominator 2, denominator 3.
The least common multiple is 6, so multiply it by 6 at the same time.
That is 6(x-2)/3=6(2x-4)/2.
See if we can make an appointment.
So 2(x-2)=3(2x-4)
Then, remove the brackets, move the term, and merge the coefficients to 1.
This is the simplest example.
More complex (x+2)/4-1= (3x-1)/3.
At this time, the least common multiple of denominator is 12.
So both sides are multiplied by 12 at the same time
pay attention to
When you multiply, you must multiply each term in the equation.
That is12 (x+2)/4-12 =12 (3x-1)/3.
About 3(x+2 )- 12=4(3x- 1)
Then remove the bracket.
Actually, it looks very troublesome.
You should ask your teacher.
Or other students who learn better.
It's much better to let him tell you something than to watch a computer.
Teachers are students who like to ask questions.
