Question

Answer 1

Distribute first

Answer 2

thats what i was going to say Jesus... >.<

Answer 3

ahahaha whatever :P

Answer 4

@cgurley86 don't do their work fir them

Answer 7

oh and welcome to OS....lolthanks @Luis_Rivera

Answer 8

k

Answer 9

so @Tayloresc sorry to get sidetracked, but you distribute the numbers in the parentheses with the number out side of it

Answer 10

you follow me so far @Tayloresc ? based from this example, can you distribute the other side of the equation?

Answer 11

....

Answer 12

Oh I'm sorry @Jamierox4ev3r I was on a different webpage yes I do

Answer 13

cool so can you distribute both of the entire equation for me? If you want, I can demonstrate for you

Answer 14

demonstrate pleased then I can do it :)

Answer 15

cool i already gave an example above (see drawing)but a good rule of thumb is below:

2(2x+2) = 4x+4. Now you try

Answer 16

2x-2?

Answer 17

ah, but do not forget the negatives: it would be -2x+2

Answer 18

if you put the two together, what do you get @Tayloresc ?

Hint: 3x+3=...

Answer 19

I'm so confused right now :( @Jamierox4ev3r

Answer 20

well, if you put the two distributed parts of the equation together, it is 3x+3=-2x+2

Answer 21

from there you should start being able to solve

Answer 22

3x+3=-2x+2
+2x +2x
---------
5x+3=2
-3 -3
-------
5x=-1
/5 /5
----
x= -0.2, or \(\large\frac{-1}{5}\)

Answer 23

3(x + 1) = -2(x - 1) + 6
3x + 3 = -2x + 2 + 6
3x + 3 = -2x + 8
3x + 2x = 8 - 3
5x = 5
x = 1

check..
3(1 + 1) = -2(1 - 1) + 6
3(2) = -2(0) + 6
6 = 6 (correct)

x = 1

Answer 24

jamierox....you forgot about the 6
