X/7+x-2/14=1/7<br> Please answer x as a fraction!
V125BC [204]

Answer:

x = \frac{1}{4}

Step-by-step explanation:

Given

\frac{x}{7} + x - \frac{2}{14} = \frac{1}{7}

Multiply through by 14 to clear the fractions

2x + 14x - 2 = 2 ( add 2 to both sides )

16x = 4 ( divide both sides by 16 )

x = \frac{4}{16} = \frac{1}{4}
