having trouble understanding the process to solve this question:

if m(�Ú6)=8x-40 and m(�Ú4)=6x+2 what are the mesures of angles 6 and 4?

Not enough information.

For example, suppose x = 10

m(angle 6) = 8x - 40
m(angle 6) = 8(10) - 40
m(angle 6) = 80 - 40
m(angle 6) = 40

m(angle 4) = 6x + 2
m(angle 4) = 6(10) + 2
m(angle 4) = 60 + 2
m(angle 4) = 62

Now suppose x = 9 ... or 11 ... or 12 ... or ...
