(2/3x) -5=7/9
2/3x = 5 + (7/9)
2/3x = 52/9
2/x=52/3
6=52x
x=3/26
2/3x = 5 + (7/9)
2/3x = 52/9
2/x=52/3
6=52x
x=3/26

2/(3x) - 5 = 7/9 ( multiplico todos por 9x)
2(9x)/3x - 5(9x) = 7(9x)/9
2.3 - 45x = 7x
6 = 7x + 45x
6 = 52x
x = 6/52
x = 3/26 ok
2(9x)/3x - 5(9x) = 7(9x)/9
2.3 - 45x = 7x
6 = 7x + 45x
6 = 52x
x = 6/52
x = 3/26 ok
