Question

13= 7+ U/3

Answer 1

@satellite73

Answer 2

solving for U ?

Answer 3

yes

Answer 4

13 = 7 + U/3 --- subtract 7 from both sides
13 - 7 = U/3
5 = U/3 -- multiply both sides by 3
15 = U

check..
13 = 7 + 15/3
13 = 7 + 5
13 = 13 (correct)

U = 15
any questions ?

Answer 5

@texaschic101 Thanks and no. I'm writing this down now.

Answer 6

@texaschic101 it says that it is wrong.

Answer 7

@texaschic101 it says simpify it as much as possible.

Answer 8

wait...I messed up

13 = 7 + U/3 -- subtract 7
13 - 7 = U/3
6 = U/3 -- multiply by 3
18 = U

check..
13 = 7 + 18/3
13 = 7 + 6
13 = 13 (correct)

sorry about that...messed up over a simple arithmetic error.
U = 18

Answer 9

okay thanks!

Answer 10

@texaschic101 you have time for one more?

Answer 11

yep...whatcha got

Answer 12

6+5V=-14
Solve For V.

Answer 13

@texaschic101

Answer 14

6 + 5V = -14 -- subtract 6 from both sides
5V = -14 - 6
5V = -20 -- divide both sides by 5
V = - 4

check..
6 + 5(-4) = -14
6 - 20 = -14
-14 = -14 (correct)

V = -4
