Question

-5(5n+2)=30 n=-8/5 please shoe me how i got this answer

Answer 1

first you multiply -5 by what is in the bracket...
-5(5n+2) = -25n -10..and that is to the left of your "=" sign

So, you now have -25n-10 = 30
you want "25n" by itself on the left side, so you add 10 to each side
25n = 30 +10
25n = 40

Next, you want to solve for "n" so you divide each side by 25
n = 40/25
n= 8/5

Answer 2

thank you so much

Answer 3

your welcome!

Answer 4

by any way what about showing work for 3(6z-1)-5(z+3)=5(z+1) z=23/8

Answer 5

ok, sure, you use the same method as I showed you up above...

First on the left of the "=", you want to multiply 3 by the bracket next to it and multiply -5 by the bracket beside it...

Answer 6

ok i am so trying to understand this all

Answer 7

18z - 3 - 5z -15 = 5z + 1

As you notice, on the right of the "=" sign I multuplied 5 by the bracket next to it

Answer 8

ok

Answer 9

once you have

18z - 3 - 5z -15 = 5z + 1

you can combine any "like" terms on each side

13z - 18 = 5z + 1

now, you want your "z's" on one side of the equl sign and your numbers on the other

Answer 10

8z = 19
z = 19/8

what did think the answer was?
