Question

simplify

16 – 4(3x – 5)

Answer 1

I forgot how to simplify algebraic expressions like these if someone pls show me step by step

Answer 2

ok so

16−4(3x−5)

you need to distribute

16+(−4)(3x)+(−4)(−5)

so that is 16+−12x+20

n combine like terms

16+−12x+20

(−12x)+(16+20)

so its gunna be

−12x+36

Answer 3

I dont understand the distributing part

Answer 4

so distributing is where you bring a number and its symbol (Negative or positive) inside the parenthesis then you multiply that number with both numbers in the parenthesis

Answer 5

I understand what it means but i dont understand how you would distribute 16−4 into(3x−5)

Answer 6

oh its where you take the negative 4 and multiply it by 3X and negative 5

Answer 7

oh so you multiply by them separately

Answer 8

yes

Answer 9

ok why did they not distribute the 16 as well

Answer 10

separately

Answer 11

16 you would use with your answer like for example 16 - any answer you get

Answer 12

sorry, i dont understand

Answer 13

ok so don't forget to bring the X down when you multiply negative 4 by 3X also negative 4 and negative 5 will make that a positive. I'm going to go step by step with you to help you out.

Answer 14

Ok can we start from the beginning

Answer 15

if thats ok with u

Answer 16

yeah we can i have no problem with that

Answer 17

ok so
16−4(3x−5)

Whats is the first step ?

Answer 18

the first step is you distribute the negative 4 over top the 3X and negative 5

Answer 19

ok so i get

Answer 20

what do i put after the 3x

Answer 21

ok multiply 4 and 3x

Answer 22

i did that

Answer 23

whats the answer you got

Answer 24

i got -12 but i dot understand what to put after the 3x do i put and addition sign or subtraction

Answer 25

you do not keep the three 3x because you just used it so now you are left with 16-(-12x) but you still have to multiply negative 4 and negative 5

Answer 26

ok so i get -5*-4 and get 20

Answer 27

yes, so now you are left with your new equation which is 16 + 12X + 20 which what you do here is something different so you have to bring the 16 over to the 20 and you subtract them

Answer 28

ok so i got 16+20+-12x
36+-12x

is that the same as the answer?

Answer 29

no, you are supposed to subtract 16 by 20 and it would have given you 4 as your answer so now you divide negative 12 by 4 and it should give you your simplified answer

Answer 30

How? i thought i was to add 16 and 20 because it says 16+20

Answer 31

no, because they were both on different sides so you subtract 16 by 20

Answer 32

ok so -12x-4

Answer 33

yes, then you divide that two meaning 12x/-4 which would give you a positive 3 and that's your simiplfied answer

Answer 34

thank you

Answer 35

no problem

Answer 36

oh if you need any more help let me know

Answer 37
