Answer
$\frac{8}{21}=y$
$\frac{2}{7}=x$
Work Step by Step
The second equation is already solved for $x$, we have to substitute this expression into the first equation:
$\frac{3}{4}y=6y-2$
$3y=24y-8$
$8=21y$
$\frac{8}{21}=y$
$x=\frac{3}{4}y=\frac{3}{4}\times\frac{8}{21}=\frac{2}{7}$
We need to check, if it is the right solution, we substitute x with $\frac{2}{7}$ and y with $\frac{8}{21}$:
$\frac{2}{7}=6\frac{8}{21}-2=\frac{6}{21}$ $\checkmark$
$\frac{2}{7}=\frac{3}{4}\times\frac{8}{21}$ $\checkmark$
