Question

de o valor de x 3x/5- 8/4 = 1/2​

Answer 1

Resposta:

x=25/6

Explicação passo-a-passo:

mmc:

5,4,2/5

1,4,2/2

1,2,1/2

1,1,1//

mmc(5,4,2)= 20

3x/5-8/4 =1/2

4.(3x)-8.(5)=10.(1)

12x-40=10

12x=10+40

12x=50

x= 50/12

Simplificando: (50÷2)/(12÷2)=25/6

x= 25/6

Answer 2

Resposta:

S = {25/6}

Explicação passo-a-passo:

$\frac{3x}{5} - \frac{8}{4} = \frac{1}{2} \\ \frac{3x}{5} - 2 = \frac{1}{2} \\ \frac{3x}{5} = \frac{1}{2} + 2 \\ \frac{3x}{5} = \frac{5}{2} \\ 6x = 25 \\ x = \frac{25}{6}$
