Answer:


x = 7

Explanation:

Given


m_2 = 6x + 8


m_6 = 8x - 6

Required

Determine x when both lines are parallel

For parallel lines, slopes must be equal.

i.e.


m_1 = m_2

In this case,


m_6 = m_2

Substitute values for m6 and m2


8x - 6 = 6x + 8

Collect Like Terms


8x - 6x = 8 + 6


2x = 14

Solve for x


x = 14/2


x = 7
