?

Answer 1

Answer & Step-by-step explanation:

- 22 = -8u + 6(u-7)

-22 = -8u + 6u - 42

8u - 6u = 22 - 42

2u = -20

u = -20/2

u = -10

Answer 2

u=2

Explanation:

8u+ 33 =-7(u-9)

Distribute

8u+ 33 =-7u+63

Add 7u to each side

8u+33+7u = -7u+63+7u

15u+33 = 63

Subtract 33 from each side

15u +33-33 = 63-33

15u = 30

Divide each side by 15

15u/15 = 30/15

u =2
