Question

3(5n+4)-4n=78

Answer 1

how did u get this

Answer 2

You do the distributive property on 3(5n+4) which says that 3(5n+4)=(3x5n)+(3x4)=15n+12. so then you have 15n+12-4n=78. which can be re written as 15n-4n+12=78. 15n-4n=11n. so you have 11n+12=78. subract 12 from each side you have 11n=66. divide both sides by 11 giving you n=6..im sorry i mis typed above

Answer 3

owe okay can u tell me if this question is write

Answer 4

4(4k-2)-1=-89
16k-8-1=-89

Answer 5

i confused now

Answer 6

so that is equivalent to 16k-9=-89 add 9 to both sides 16k=80. k=80/16=5

Answer 7

so K=5

Answer 8

yes

Answer 9

owe okay

Answer 10

im really confused on this question
5+6(1-4x)=-109

Answer 11

so its alot like the other ones. it could be rewritten as 6(1-4x)+5=-109. does that help you with where to start?

Answer 12

11(1-4x)=-109
11-44x=-109
-109=-98
x=-98

Answer 13

you have to do the distributive property first. so
6(1-4x)+5=-109
6-24x+5=-109
11-24x=-109
24x-11=109
24x=120
x=120/24=5
