Question

Solve –4(x + 4) = 16 i forgot how to do the step can you please help me:)

Answer 1

if four times a number is 16 then the number is 16 divided by 4

Answer 2

don't i have to do distributive property ?

Answer 3

its easier to divide the whole equation by -4 first, then u don't need to use distributive property ...

Answer 4

x=-8 right

Answer 5

so i divide negative four by 16? or the opposite ?

Answer 6

u divide 16 by (-4)

Answer 7

i get -4?

Answer 8

yes :)
so u have
x+4=-4
can u solve further ?

Answer 9

-4(-8+4)=16
-4(-4)=16
16=16

Answer 10

i subtracted both sides by 4 and got -8 for my final answer ; x= -8

Answer 11

thats correct :)
now u understand ?
ask if still in any doubts anywhere.....

Answer 12

Yayy:) well one little question, i didn't really get why i had to divide 16 by 4?

Answer 13

you dont

Answer 14

i got alittle confused

Answer 15

to be honest

Answer 16

oh actually you do

Answer 17

since the main aim was to isolate x
and -4 was "multiplied" by (x+4),
so to isolate, u divide both sides by -4
so that only x+4 remain on left.
got this ?

Answer 18

-4(x+4)=16
x+4=-4
x+4-4=-4-4
x=-8

Answer 19
