Answer:
u = 13
Step-by-step explanation:
2 (3u + 7) = - 4 (3 - 2u)
6u + 14 = - 12 + 8u
6u - 8u = - 12 - 14
- 2u = - 26
- u = - 26/2
- u = - 13
u = 13
Answer:
u = 13
Step-by-step explanation:
2 (3u + 7) = - 4 (3 - 2u)
6u + 14 = - 12 + 8u
6u - 8u = - 12 - 14
- 2u = - 26
- u = - 26/2
- u = - 13
u = 13
