Question

Resolva a equação 2x/3 = x- 3/5

Answer 1

2x/3 = x - 3/5        

2x/3 = 5x/5 - 3/5  m.m.c. = 15

10x/15 = 15x/15 - 9/15
10x = 15x - 9
9 = 15x - 10x
5x = 9
x = 9/5

Answer 2

2x / 3 = x - 3 / 5
mmc de (3,5)
3,5/3
1,5/5
1,1

(3*5) = 15

5*(2x) = 15x - 9
10x = 15x - 9
- 15x + 10 = - 9
- 5x = - 9 .(-1)
5x = 9
x = 9/5
