Help.

Answer 1

Hi,

Here are the solutions.

1.

$6 = x + \frac{2}{3} \\ - x + 6 = \frac{2}{3} \\ - x = \frac{2}{3} - 6 \\ - x = - \frac{16}{3} \\ \\ x = \frac{16}{3} = 5 \frac{1}{3} \: \: \: \: \: \: \: \: \: (result)$


2.

$13 + \frac{w}{7} = - 18 \\ \\ - 5 + \frac{w}{7} \: \: \: \: \: \: \: (result)$


3.

$17 = - 13 - 8x \\ 8x + 17 = - 13 \\ 8x = - 13 - 17 \\ 8x = - 30 \: \: \: | \: \div 8 \\ \\ x = - \frac{15}{4} = - 3 \frac{3}{4} \: \: \: \: \: (result)$


Hope this helps.
