Question

help please ! -4x+-2=3x-10 i did all the work before i'm just not sure what to do after

Answer 1

Your next step is to add 2 to both sides. What do you get?

Answer 2

-8

Answer 3

so

-4x+-2=3x-10

becomes

-4x=3x-8

Answer 4

Now subtract 3x from both sides

Answer 5

so it would be -x=8

Answer 6

-8

Answer 7

good, x = -8 is your final answer

Answer 8

thank you :)

Answer 9

oh wait, one sec

Answer 10

it should be

-x=-8

which turns into

x = 8

Answer 11

oh.. okay ! thank you

Answer 12

can you help me with another one...

Answer 13

hold on, let me check something real fast

Answer 14

:p okay

Answer 15

Isn't the answer actually x = 8/7?

Answer 16

thats not one of my options...

Answer 17

oh my bad, i made an error, here's the correct way to do this

-4x+-2=3x-10

-4x=3x-10+2

-4x = 3x - 8

-4x-3x = - 8

-7x = -8

x = -8/(-7)

x = 8/7

Not sure how I missed that, but oh well

Answer 19

sure

Answer 20

6x − 2(x + 1) = 3x − 10

Answer 21

6x − 2(x + 1) = 3x − 10

6x − 2x - 2 = 3x − 10

4x - 2 = 3x − 10

4x = 3x − 10 + 2

4x = 3x − 8

4x -3x = -8

1x = -8

x = -8

Answer 22

So the error you made was thinking that 6x - 2x was -4x

it should be 6x - 2x = 4x

Answer 23

oh.. im sorry :p

Answer 24

that's ok

Answer 27

After a discount of 20%, the price of a pair of shoes, including tax, is $66.91. The following equation can be used to find x, the price of the pair of shoes without the discount.

x - 0.2x + 0.06(x - 0.2x) = 66.91

What is the price of the pair of shoes without the discount?

Answer 28

They want you to solve for x

Answer 29

x - 0.2x + 0.06(x - 0.2x) = 66.91


x - 0.2x + 0.06(0.8x) = 66.91


x - 0.2x + 0.048x = 66.91


0.848x = 66.91


Can you take it from here?
