Question

-4(x+3)=16 how would this be worked out?

Answer 1

Okay, what is the first step?

Answer 2

Distributive property
multiply -4 to x and 3 in the parentheses

Answer 3

Okay, so now what does the equation look like after doing that?

Answer 4

-12x=16

Answer 5

Not quite. Let start with -4 times x. What do you get?

Answer 6

-4x
right?

Answer 7

Yep, okay, now -4 times 3.

Answer 8

-12

Answer 9

Yep, so now we have
-4x - 12 = 16

What's next?

Answer 10

gotta get x by itself so -4x on both sides

Answer 11

no plus -4x not minus

Answer 12

on both sides

Answer 13

Let's start by getting rid of the -12 that way we don't have to move the x.

Answer 14

right that makes more sense lol

Answer 15

-4x=32

Answer 16

then u divide by -4 on both sides and u get x=-8

Answer 17

Careful with the addition:
-4x - 12 + 12 = 16 + 12
-4x = ?

Answer 18

the 12+ 12 cancels out 12+16=32
-4x=32
divide -4 on each side -4/-4 cancles out
32/-4=-8



right??

Answer 19

12 + 16 = 28

Answer 20

But you're right on with the dividing by -4.

Answer 21

opps got in a hurry leme fix it

Answer 22

No worries, I do it all the time. (Probably thought 16 and 16 instead, in that case you'd be right with the 32.)

Answer 23

lol x=-7

Answer 24

Yep! You got it!
