Question

dada a equaçao , calcule o valor de x. 2x/4 - 5/3=x -7/2

Answer 1

Resposta:

$x = \frac{11}{3}$

Explicação passo-a-passo:

$\frac{2 x }{4} = \frac{x}{2} \\ \\ \frac{x}{2} - \frac{5}{3} = x - \frac{7}{2} \\ mmc(2e3) = 6 \\ então : \\ 6( \frac{x}{2} ) - 6( \frac{5}{3} ) = 6x - 6( \frac{7}{2} ) \\ 3x - 10 = 6x - 21 \\ 3x = 21 - 10 \\ 3x = 11 \\ x = \frac{11}{3}$

Answer 2

2x/4 - 5/3=x - 7/2
X/2 - 5/3 = x - 7/2
X/2 - x = - 7/2 + 5/3
Mmc (2,3)= 6
(3x - 6x)/6 = (-3.7 + 2.5)/6
- 3x = - 21 + 10
- 3x = - 11
3x = 11
x = 11/3
