Question

Resolva as equações
a) 3x+2/x+1 = 3/2

b)2x-1/3-4x = 1/3

Answer 1

Resposta:

a) x = $-\frac{1}{3}$

b) x = $\frac{3}{5}$

Explicação passo-a-passo:

a)

$\frac{3x+2}{x+1} =\frac{3}{2}$

6x + 4 = 3x + 3

6x - 3x = 3 - 4

3x = -1

x = $-\frac{1}{3}$

b)

$\frac{2x-1}{3-4x} =\frac{1}{3}$

6x - 3 = 3 - 4x

6x + 4x = 3 + 3

10x = 6

x = $\frac{6}{10}$ = $\frac{3}{5}$
