Question

I dont what to do here as well also can you guys explain it to mee!

Answer 1

-34/15

Explanation:

-5/3 = (-5/4)u - 9/2

5/3 = (5/4)u + 9/2

12(5/3) = 12(5/4)u + 12(9/2)

20 = 15u + 54

15u = -34

u = -34/15

Answer 2

-5/3 = (-5/4)u - 9/2

5/3 = (5/4)u + 9/2

12(5/3) = 12(5/4)u + 12(9/2)

20 = 15u + 54

15u = -34

u = -34/15
