Answer 1

@Secret-Ninja

Answer 2

@sleepyjess

Answer 3

Distribute and solve for a.

Answer 4

Can you attempt to do that for me?

Answer 5

@pielover123 Just do what I taught you before, you move the variable to their own side of the equation and solve it, just like in the last question.

Answer 6

ok

Answer 7

Its the same thing, just don't over think it. :)

Answer 8

ok i did it on paper and i got -12

Answer 9

so would a= -12?

Answer 10

Hmm... not quite... a is 4... Would you mind showing me how you did it?

Answer 11

ok first what i did is like order of operation

Answer 12

like i did -2(1+5a)= 6-2=4

Answer 13

-2(1+5a)= -6(a+3)

When you distribute brackets..

-2-10a=-6a-18

Answer 14

How would that be -12?

Answer 15

then i did (-6a+3)= -3 with would add -3+4= 12

Answer 16

did i get it right @Secret-Ninja

Answer 17

Lets start from the part where @dtan5457 distributed the brackets.
-2-10a=-6a-18

This is where you begin to get the variable (a) by it self.

Answer 18

ok

Answer 19

-2-10a=-6a-18

Move -2

-10a=-6a-18+2

Move -6a

-10a+6a=-18+2

Answer 20

ok im wirting it on paper

Answer 21

-18+2=-16
and
-10a+6a=-4a

Answer 22

So...
-4a = -16

Answer 23

so it is -16

Answer 24

Since -4 is multiplied to a, you divide it to get it to the other side.

Tell me, what is -16 divided by -4?

Answer 25

a has to be a, not -4a, -a, 4a, nothing, just A.

Answer 26

ok it is 4 @Secret-Ninja

Answer 27

yep. good job everyone.

Answer 28

so the answer is 4

Answer 29

thanks guys!!!

Answer 30

Yes, it is 4, good job! :D

Answer 31

No problem. :)
