Answer:
8
Step-by-step explanation:
you want to set it up like this
8/20 and 6/2x-1
then you cross multiply
so 8(2x-1) = 16x-8
and 20*6 = 120
then you do 120= 16x-8
add 8 to both sides (you want x by it's self so to get rid of a -8 you have to add 8)
128= 16x
(divide both sides by 16)
128/16= 8
8=x
