Question

What value of x satisfies the equation x/6-1/5=7/30

Answer 1

We need to isolate x in order to find x. However, we need to have common denominators first.
$\frac{5x}{30}- \frac{6}{30} = \frac{7}{30}$
$\frac{5x}{30}= \frac{13}{30}$
Multiply by 30 on both sides.
$5x=13$
Divide by 5 on both sides to isolate x.
$x= \frac{13}{5}$
