Simplify the left hand side by multiplying the terms in the parenthesis by 3/4, i.e. divide them by 4 and multiply them by 3:

Subtract 6x from both sides:

Subtract 2 to both sides:

3x - 2 = x + 10
So, 2x = 12 and x = 6
The correct answer is <span>C. Lines m and n have the same slope so they are parallel. The slope = 2/3 </span>
