Alternate exterior angles(AEA).
Given their relationship the angles are congruent.
8x-71=5x+7
3x-71=7
3x=78
X=26
Im not sure what you are asking, but i will say the answer is
<span>Total number of times the activity is performed: Number of times an event occurs</span>
3k - (k-2) = (k-2) - (k+7) 3k = (k-2) - (k+7) + (k-2) 3k = 2(k-2) - (k+7) 3k = 2k - 4 - k - 7 3k = k - 11 2k = -11
k = -5.5
