y=-\frac{3}{4}+\frac{2}{7}
Add \frac{2}{7} to both sides.
y=-\frac{21}{28}+\frac{8}{28}
Least common multiple of 4 and 7 is 28. Convert -\frac{3}{4} and \frac{2}{7} to fractions with denominator 28.
y=\frac{-21+8}{28}
Since -\frac{21}{28} and \frac{8}{28} have the same denominator, add them by adding their numerators.
y=-\frac{13}{28}
Add -21 and 8 to get -13.
