Question

I need help with two problems I'm stuck on:
Solve: -2x - 13 = 8x + 7

-2

2

-6

6
and
Solve: -4(2x - 1) = -6(x + 2) - 2

-5

5

9

-9

Answer 1

for the first problem you add 13 from both sides then subtract 8x from both sides then divide by 10

Answer 2

the second one im not sure how

Answer 3

For the second one, you distribute the -4 and -6

Answer 4

so 13+7=20
-2x=8x+20 ?

Answer 5

You multiply 2x by -4 giving you -8x, and -1 by -4 giving you 4. (for the left side of the equation.)

Answer 6

yes then subtract 8x on both sides

Answer 7

what would you get when you subtract 8x from -2x

Answer 8

so -2x-8x= -10

Answer 9

or positive 10?

Answer 10

oh so 2!

Answer 11

briajosephs Im a little confused about the second one

Answer 12

The answer's negative two for the first equation.

Answer 13

oh okay :)

Answer 14

no it would be -10x then divide by -10 and what do you get?

Answer 15

Oh and for the second equation, the hardest part part is to distribute the outer numbers into the parenthesis

Answer 16

I got 2, but it was negative 2

Answer 17

there is your answer.x=-2

Answer 18

Oh okay! I understand the second on know, give me a scond to solve it

Answer 19

This website explains the distributive property much better than I can lol

Answer 20

do you get how to solve the first equation now?

Answer 21

yes I understand the first one, Thanks:)
For the second on I got -8x- (-4)=(-6x+-12)-2
I don't know if that was the right step

Answer 22

It was! Two negatives equal a positive, so it'll be -8x + 4

Answer 23

i would just go to the website briajosephs gave cause i dont undertand the second equation that well

Answer 24

oh okay! Then I just solve what's in parentheses right?

Answer 25

Your new equation is -8x + 4 + -6x - 12 - 2 really because to solve the parenthesis you'd have to distribute again and there's really no need for that

Answer 26

-8x + 4 = -6x - 12 - 2* sorry lol

Answer 27

Now you just combine like terms on the right

-8x + 4 = -6x -14

Then subract -8 on both sides

4 = 2x -14

And add 14 on both sides

18 = 2x

Then divide two and you got your answer!

Answer 28

So the answer is 9! Thank you so much! you really helped ^-^

Answer 29

Aw no problem love! Any time (:
