First, you multiply everything by 8, so you get:
Then, you develop, and you get:
You simplify
by dividing by 2, and you get:
= 2x
Then, you put known numbers apart (numbers without x), and unknown numbers apart (numbers with x), which means you move 2x to the other part (and it become -2x), and
to the other part ( and it become
), so you get:
you subtract and you get:
then, you move 22 to the other part, and since it's a multiplication, it become a division, so you get:
As you know,
, and dividing 2 fraction is equal to multiplying the first fraction by the inverse of the second fraction, so you get:
You multiply and you get:
4 and 154 have a common factor which is 2, so you divide each one by 2, and you get:
you divide, and you get:
So,
Hope this Helps! :D
