Solve {c}{frac{125-v_{1}}{2}+v_{2}-v_{1}-frac{v_{1}-75}{3}=0}{frac{v_{2}-125}{7+9.9}+0.5v_{3}-v_{2}+v_{1}=0}{125-v_{1}=v_{3}}{c=frac{125-v_{2}}{7+9.9}}

Solve for v_1, v_2, v_3, c

v_{1} = \frac{23225}{207} = 112\frac{41}{207} \approx 112.198067633

v_{2} = \frac{73400}{621} = 118\frac{122}{621} \approx 118.196457327

v_{3} = \frac{2650}{207} = 12\frac{166}{207} \approx 12.801932367

c=\frac{250}{621}\approx 0.40257649
