15x - 30 = 10x + 5
15x - 10x -30 = 5
5x - 30 = 5
5x = 5 + 30
5x = 35
Divise by 5 on both sides to isolate x
x = 7 => answer

The Angles are adjacent and since they are both on a straight line it means that the sum of the angle is 180 degrees, so we get the equations:

$(6x) + (x - 2)=180\\7x = 182\\x=26$

So x = 26.

Hope that helps!
