Answer:
u=4/5
Step-by-step explanation:
First, parentheses/multiply on both sides.
2u-2-6=20u-20-3u <--- two negatives make a positive
Next, add/subtract like terms.
2u-8=17u-20
Then, add 8 to both sides.
2u=17u-12
Finally, get "u" by itself. Subtract "17u" to both sides and then divide "-15" to both sides
-15u=-12
u=4/5
