Question

x-2(x+10)=12 please explain

Answer 1

Distribution property.
a(b-c)=ab-ac

Answer 2

-2(x+10)=?

Answer 3

huh?

Answer 4

So -2(x+10)=-2(x)+(-2)(10)=??

Answer 5

Distribute:
x - 2 ( x + 10 ) = 12
x- (2*x) + (2*10) = 12

x - 2x + 20 = 12

Then you combine like terms~ Do you know how to do that? :D

Answer 6

@arabpride not really im kind of slow with it

Answer 7

What grade are you in? If I may ask?

Answer 8

Answer 9

The good times *-*

Answer 10

:)

Answer 11

Sorry - i was afk >.> okay now ill help u finish :D

Answer 12

@arabpride it okay i understand

Answer 13

x - 2x - 20 = 12
Subtract like terms You get
-1x-20=12
Add 20 on both sides

-1x - 20 = 12
+20 +20
--------------------
-1x =32
x=-32

Answer 14

Combine like terms: just basically means to put together common variables and whole numbers etc.~

x - 2x + 20 = 12
-20 -20

x - 2x = -8
-x = -8

we need a POSITIVE answer so we multiply BOTH sides be -1

(-1)*-x = (-1)*-8
x = 8

:D

Answer 15

lol The conflicting answers.

Answer 16

Answer 20

Okay lemme correct myself >.>

Answer 21

x-2(x+10)=12
-32- 2(-32+10)=12
-32-2(-22)=12
-32+44=12
12=12

Answer 22

Yay I was correct :)

Answer 23

Look at us. We are mathlete' but are stumbling on this problem.. lol

Answer 24

wait im confused who has the right answer?? :/

Answer 25

Wait where did 32 come from? o-o

Answer 26

x - 2x - 20 = 12
Subtract like terms You get
-1x-20=12
Add 20 on both sides

-1x - 20 = 12
+20 +20
--------------------
-1x =32
x=-32
