Question

equação de 1° grau : (2(x+5))/3=(5x+1)/2

Answer 1

$\dfrac{2(x+5)}{3} = \dfrac{5x+1}{2} \to~~ \\\\\ \dfrac{2x+10}{3} = \dfrac{5x+1}{2} \to~~ mmc=6\\\\\ 4x+20=15x+3\to\\\\\\ 4x-15x=3-20\to\\\\\\ -11x=-17~(-1)\to\\\\\\ 11x=17\to\\\\\\ \boxed{ x=\frac{17}{11} }$

Answer 2

2(x + 5)  =  5x + 1
     3              2

2x + 10   =  5x + 1
    3                2

Multiplicar em "cruz":

2.(2x + 10) = 3.(5x + 1)
4x + 20 = 15x + 3
20 - 3 = 15x - 4x
17 = 11x
17 = x
11

x =  17
       11
