Answer 1

HI!!

Answer 2

Hey

Answer 3

Combine like terms I think

Answer 4

@Cammie21 you need to add all the like terms.

-2a + 5a -1a = ?

Answer 5

combine like terms on the left first \[-2a+5a=?\]

Answer 6

I don't know how to work it out seriously I have an F in math class

Answer 7

4

Answer 8

lets go nice an slow then

Answer 9

Wait, are you sure you typed the question correctly? The previous question didn't have an equal sign in the middle.

Answer 10

yea I typed it right

Answer 11

the left side of the equal sign looks like this \[-2a+5a\]

Answer 12

you need to combine these, which really means compute \(5-2\) and put an \(a\) next to it

Answer 13

Oh, ok then. I'll let Misty help you!

Answer 14

I did that.

Answer 15

Once you combine like terms on the left get a to one side

Answer 16

ok

Answer 17

You guys still there

Answer 18

yes

Answer 19

Now I have 3a=-1a-12

Answer 20

did you get \(3a\) on the left?

Answer 21

ok good

Answer 22

now you want all the stuff witi \(a\) in it on one side of the equal sign
you can get that by adding \(a\) to both sides

Answer 23

\[3a=-1a-12\\3a+a=12\] combine like terms again on the left

Answer 24

ok got that

Answer 25

did you get \[4a=12\]?

Answer 26

yes

Answer 27

ok now you have a choice, you can just think, what times 4 is 12?

Answer 28

3

Answer 29

which is the same as writing \[x=12\div 4\]

Answer 30

yes, 3 is your answer

Answer 31

ok thank you I have more

Answer 32

i bet !

Answer 33

-9+4x=6+1x

Answer 34

$-2a+5a=-1a-12\quad:\quad a=-3$−2a+5a=−1a−12 : a=−3

Steps

$-2a+5a=-1a-12$−2a+5a=−1a−12


$\mathrm{Refine}$Refine

$3a=-a-12$3a=−a−12



$\mathrm{Add\:}a\mathrm{\:to\:both\:sides}$Add a to both sides

$3a+a=-a-12+a$3a+a=−a−12+a


$4a=-12$4a=−12



$\mathrm{Divide\:both\:sides\:by\:}4$Divide both sides by 4

$\frac{4a}{4}=\frac{-12}{4}$4a4 =−124

$a=-3$a=−3

Answer 35

hold on a sec

Answer 36

ok

Answer 37

ok hold on a second

Answer 38

okie

Answer 39

i made a mistake

Answer 40

yep

Answer 41

it should have been \[4a=-12\] so \[a=-12\div 4=-3\]

Answer 42

sorry if it took a bit for me to respond

Answer 43

it's ok both of you.

Answer 44

help me on this one. -9+4x=6+1x
