Question

(x+3)2/5=(x+1)=
Qual é o valor da resposta ?

Answer 1

$(x+3).\frac{2}{5}=x+1\\ \\ 2(x+3)=5(x+1)\\ \\ 2x+6=5x+5\\ \\ 3x=1\\ \\ x=\frac{1}{3}$

Answer 2

$(x+3) \dfrac{2}{5} =(x+1)\to\\\\ \dfrac{2x+6}{5} =x+1\to ~~multiplique~~cruzado:\\\\ 2x+6 = 5x+5\to\\\\ 2x-5x=5-6\to\\\\ -3x=-1~(-1)\to\\\\ 3x=1\to\\\\ \large\boxed{x= \frac{1}{3} }$
