a. no
b.no

#### Work Step by Step

To find out if an ordered pair is a solution you need to insert the values of the variables into the equation. If the answer of the system is true, the pair is a solution, if not it isn't.
a. $4\times0=1-1<=>0=0$
$0-3\times1=-8<=>-3\ne-8$
b.$4\times\frac{1}{6}=1-\frac{1}{3}<=>\frac{2}{3}=\frac{2}{3}$
$\frac{1}{6}-3\times\frac{1}{3}=-8<=>-\frac{5}{6}\ne-8$
