Question

1)Resolva
$a)5x + \frac{1}{2} = \frac{x}{8} + \frac{3}{4}$
$b) \frac{3}{7}x + 10 = x + 8$
$c) \frac{1}{3} x + 3 = x + 1$
​

Answer 1

a)

$5x + \frac{1}{2} = \frac{x}{8} + \frac{3}{4} \\ 40x + 4 = x + 6 \\ 39x = 2 \\ x = \frac{2}{39}$

b)

$\frac{3}{7}x + 10 = x + 8 \\ 3x + 70 = 7x + 56 \\ 4x = 14 \\ x = \frac{7}{2}$

c)

$\frac{1}{3} x + 3 = x + 1 \\ x + 9 = 3x + 3 \\ 2x = 6 \\ x = 3$
