Question

Can some one help me ?????

Answer 1

$\frac{6}{7}v-\frac{7}{4}=-\frac{3}{2}|\cdot28\\ 24v-49=-42\\ 24v=7\\ v=\frac{7}{24}$

Answer 2

$\frac{6}{7}v-\frac{7}{4}=-\frac{3}{2}\ \ \ \ \ |multiply\ both\ sides\ by\ LCM(7;\ 4;\ 2)=28\\\\28\times\frac{6}{7}v-28\times\frac{7}{4}=28\times(-\frac{3}{2})\\\\4\times6v-7\times7=14\times(-3)\\\\24v-49=-42\ \ \ \ \ \ |add\ 49\ to\ both\ sides\\\\24v=7\ \ \ \ \ \ |divide\ both\ sides\ by\ 24\\\\\boxed{v=\frac{7}{24}}$
