Question

ajudaaa 2(x-1)/3=(3x+6)/5

Answer 1

2(x-1)/3=(3x+6)/5
10(x-1)/15=3(3x+6)/15
10(x-1)=3(3x+6)
10x-10=9x+18
10x-9x=18+10
x=28

Qualquer dúvida só chamar ;)

Answer 2

2(x - 1)/3 = (3x + 6)/5
(2x - 2 )/ 3 = (3x + 6)/5
5.(2x - 2) = 3.(3x + 6)
10x - 10 = 9x + 18
10x - 9x = 18 + 10
x = 28

Espero ter ajudado!
