Answer 1

Resposta:

Olá bom dia!

Multiplique cruzado e iguale.

$\frac{4x}{5} =\frac{x+1}{3}$

3*(4x) = 5*(x+1)

12x = 5x + 5

12x - 5x = 5

7x = 5

Resposta:

x = $\frac{5}{7}$

Answer 2

$\large \boxed{ \begin{array}{l} \sf \dfrac{4x}{5} = \dfrac{x + 1}{3} \\ \\ \sf{12x = 5(x + 1)} \\ \\ \sf{12x = 5x + 5} \\ \\ \sf{12x - 5x = 5} \\ \\ \sf{7x = 5} \\ \\ \sf{x = \dfrac{5}{7} }\end{array}}$
