Question

4/7 is the result when 1/2 and x are added.

Answer 1

4/7=1/2+x

Find a common demominator. ( sorry I spelled it wrong)
8/14=7/14+x

Subtract 7/14 from each side.
8/14-7/14=7/14-714+x
1/14=x
1/14 is the answer

Answer 2

Answer:

$\frac{1}{14}$

Step-by-step explanation:

$\frac{4}{7}$ is the result when 1/2 and x are added.

Frame an equation using the given statement

$\frac{4}{7} =\frac{1}{2}+x$

To solve the equation for x , subtract 1/2 on both sides

$\frac{4}{7} - \frac{1}{2}=x$

To add or subtract fractions, the denominator should be same

LCD is 14

$\frac{8}{14} - \frac{7}{14}=x$

Now subtract the fractions

$\frac{1}{14}=x$

$\frac{4}{7}$ is the result when 1/2 and  $\frac{1}{14}$ are added.
