Question

$\frac{x}{3} + \frac{x}{5} + \frac{35}{1} = \frac{x}{1}$
como achar o valor do X ?​

Answer 1

Resposta:

x=75

Explicação passo-a-passo:

X/3+X/5+35/1=X/1

X/3+X/5+35=1

5X+3X+525=X

8x+525=15X

8X-15X=-525

-7X=-525 (-1)

X=75

Answer 2

x/3+x/5+35/1=x/1
5x/15+3x/15+525/15=15x/15
5x+3x+525=15x
5x+3x-15x=-525
-7x=-525(-1)
7x=525
x=525/7
x=75
