Question

Quanto é 3x/4-1/2=x/8+1?

Answer 1

$\frac{3x}{4} - \frac{1}{2} = \frac{x}{8}+1 \to mmc=8\\\\ 6x-4=x+8\to \\\\ 6x-x=8+4\to \\\\ 5x=12\to \\\\ x= \frac{12}{5}\ ou \\\\ x=2,4$

Answer 2

$\frac{3x}{4} - \frac{1}{2} = \frac{x}{8} + 1 \\ \\ \frac{6x}{8} - \frac{4}{8} = \frac{x}{8} + \frac{8}{8} \\ \\ 6x - 4 = x + 8 \\ 6x - x = 8 + 4 \\ 5x = 12 \\ x = \frac{12}{5}$
