Question

2x/3+1/2-×/4=5 resultado​

Answer 1

$\frac{2x}{3} + \frac{1}{2} - \frac{x}{4} = 5$

$mmc = 12$

$\frac{8x}{12} + \frac{6}{12} - \frac{3x}{12} = \frac{60}{12}$

$8x + 6 - 3x = 60$

$8x - 3x + 6 - 6 = 60 - 6$

$5x = 54$

$\frac{5x}{5} = \frac{54}{5}$

$x = \frac{54}{5}$

Answer 2

Resposta:

x = 54/5

Explicação passo-a-passo:

2x/3+1/2-×/4=5

2x/3 - x/4 = 5 - 1/2

MMC (3,4,2)= 12

(4.2x - 3x)/12 = (12.5 - 6.1)/12

(8x-3x) = (60-6)

5x = 54

x = 54/5

Obs.:

MMC

3,4,2: 2

3,2,1: 2

3,1,1: 3

1,1,1 = 2.2.3 = 12
