Question

-2 ( q+8) + 2( 4q-3) = 2( 4q+3)

Answer 1

Can you multiply these out? :o)

Answer 2

-2 - 16 + 8q - 6 = 8q + 6

Answer 3

Great! So now combine like terms:

-2q-16+8q-6=8q+6
6q-22=8q+6

Do you see how I got that?

Answer 4

wait how did u get that

Answer 5

Well when adding like terms, you're going to add the variables and then the regular numbers without variables. So:

On the left side of the equal sign:

-2q-16+8q-6
-------------
-2q+8q=6q
-16+(-6)= -22

Therefore: 6q-22

So, 6q-22=8q+2

The right side had no like terms to combine. Do you understand now?

Answer 6

yes

Answer 7

Now, we are going to get q on the same side of the equation, so:

6q-22=8q+2
-6q -6q
^this cancels the 6q. 6q-6q=0.

-22=2q+2

Do you understand that? :o)

Answer 8

So, now, we're going to get q alone. So, we need to get rid of the +2 and the *2. So:

-22=2q+2
-2 -2
^This cancels. 2-2=0

-24=2q

Now, 2q is multiplying, so the opposite will be to be divide. So:

-24=2q
/2 /2
^This will cancel. 2/2=1. And 1q is the same as just q.

Can you figure out the value of q now? :o)

Answer 9

how did u get plus 2 when it was plus 6?

Answer 10

12! :)

Answer 11

Oops:

6q-22=8q+6
-6q -6q

-22=2q+6
-6 -6

-28=2q
/2 /2

-14=q
