3v+2 = 7v-6
3v-7v = -6-2
-4v = -8
v = 2
then the length of QS = 3(2)+2 = 6+2 = 8
and the length of TV = 7(2)-6 = 14-6 = 8
The Alternate Interior Angle theorem states that when the lines are parallel, the alternate interior angles are equal. Since lines AB and CD are parallel, m∠ACD and m∠BAC are equal. So, the equation would be

or

.
