Question

2(u-1)-6= -5(-4u+4) -3u

Answer 1

u=4/5

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

Answer 2

u = 4/5

Explanation:

Expand

2u - 2 - 6 = 20u - 20 - 3u

Rearrange with like terms on either side

12 = 15u

u = 4/5
