Answer 10

now distribue you 4

Answer 11

(x + 5) - 2(4x - 1) = 0,
combine x+5 with -8x+2 and get -7x + 7 =0
solve for x from here

Answer 12

-2 not 4

Answer 13

so -2 x 4 and -2 x -1

Answer 14

you guys are giving me different ways to solve but i only need one

Answer 15

@iuytyuioiuytyuiop listen to me ig

Answer 20

ok guys one last thing

Answer 21

what topic is this called?

Answer 22

you mutilpy -2 x 4 and -2 x -1

Answer 23

so if te 2 number is parthesses you know to multiply going on between them 1 is equalled to 0

Answer 24

so i can look it up and practice more similar problems

Answer 25

then

Answer 26

@supie or @darkknight do you know what the topic is called?

Answer 27

now combine like trems so with what i have already said you should have 5+x-8x+2

Answer 28

so now you combine 8x and x to get 9 x

Answer 29

my life is on the LINE

Answer 30

HELP

Answer 31

what topic is this called?

Answer 32

and you get 5+9x+2

Answer 33

is it a polynomial or something else?

Answer 34

now you need to get the x alone
so you - 9 to both sides so you get -4+9x

Answer 35

there both 0 bec any number times it self is 0 so x-5=0 and x+2=0 so on the x-5 it o you have to + on both sides so it = 5

Answer 36

then divide by nine

Answer 37

-4/9 is what and thats your answer

Answer 38

thank you

Answer 39

np

Answer 40

wait

Answer 41

yea

Answer 42

in on the x-2=0 you have to - on both sides that is negative is =5,-2

Answer 43

can you tell me what this topic is so i canpractice similar problems?

Answer 44

mathmatics

Answer 45

it mostly just multply if you then you have to add on both sides

Answer 46

i mean like is it called polynomials or

you can also do ixl

Answer 52

ok

Answer 53

it expressions

Answer 54

it is very helpful tool as well

Answer 55

its expressions?!

Answer 56

with absolute value

Answer 57

yes

Answer 58

is he right?

Answer 59

yes

Answer 60

suple?

Answer 61

but it real expression in the right word

Answer 62
