Question

qual o valor de X que satisfaz a equaçao [tex]2 ( X -1 )/3 + X+2/2 = 1

Answer 1

Resposta: x = 4/7

Explicação passo-a-passo:

2( x- 1)/3 + x + 2/2 = 1

2x - 2/3 + x +2/2 = 1         mmc 1,2 e 3 = 6

4x - 4/6 + 3x + 6/6 = 6/6   elimina denominador

4x - 4 + 3x + 6 = 6

7x + 2 = 6

7x = 6 -2

7x = 4

 x = 4/7

bons estudos

Answer 2

Resposta:

3/7

Explicação passo-a-passo:

$\frac{2x-1}{3} + \frac{x+2}{2} = 1\\\\MMC 3,2 = 6\\\\4x-2 + 3x+6 = 1\\\\\frac{4x-2+3x+6}{6} = 1\\\\\frac{7x+3}{6} = 1$

Passa o 6 multiplicando

7x+3 = 6

7x= 6-3

7x = 3

x = 3/7
