How do you solve #2x-5/9 = (7x+8)/9#?

2 Answers

First of all, you multiply everything by 9 so:
#2x-5/9 = (7x+8)/9#
#<=>18x - 5 = 7x+8#
then you bring x to the first class, and the numbers to the second
#<=>18x -7x = 8+5#
#<=>11x = 13#
#<=>x=13/11#

#x=13/11#

Explanation:

Multiply everything by 9 to remove the fractions.

#18x-5=7x+8#

add 5 to both sides

#18x=7x+13#

subtract #7x# from both sides

#11x=13#

#x=13/11#
