Question

2x+3.(x+1)=5.(2x-1) pfvr me ajudem é pra amanhã

Answer 1

Olá, boa noite!

Resposta:

$\boxed{\mathsf{x =\dfrac{8}{5}}}$

Explicação passo-a-passo:

$\mathsf{2x +3 \cdot (x+1) = 5 \cdot (2x-1)}$

$\mathsf{2x + 3x + 3 = 10x -5}$

$\mathsf{5x-10x=-5-3}$

$\mathsf{-5x=-8 \ \cdot (-1)}$

$\mathsf{5x=8}$

$\mathsf{x =\dfrac{8}{5} \ \overrightarrow {ou} \ 1,6}$

Answer 2

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

$2x + 3x + 3 = 10x - 5$

$5x + 3 = 10x - 5$

$5x - 10x = - 5 - 3$

$- 5x = - 8$

$x = \frac{8}{5} = 1.6$
