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
