Question

2(x – 7) = 10x + 18

Answer 1

You need to use the distributive property.

Answer 2

So 2x-7=10x+18

Answer 3

im sorry 2x-18=10x+18

Answer 4

what happened to the 7

Answer 5

still there...

Answer 6

you used the distributive property and multiplied it by 2.

Answer 7

and you multiplied x by 2 to get rid of the parenthesis.

Answer 8

so 2*7 - 2*x?

Answer 10

no 2*x-2*7 you keep the numbers where you found them

Answer 11

so now you need to solve for x

Answer 12

Simplify:
\[2(x−7)=10x+18\]
Distribute: \[(2)(x)+(2)(−7)=10x+18\]
\[= 2x+−14=10x+18\]
\[2x−14=10x+18\]

Answer 13

Subtract 10x from both sides: \[2x−14−10x=10x+18−10x\]
What does that equal? @LoveIt

Answer 14

or you could subtract 2x from each side

Answer 15

um 4 and 8?

Answer 16

\[2x - 10x = ?\]

Answer 17

-8

Answer 18

Yes, so the equation would look like this: \[−8x−14=18\]
Now, add 14 to both sides: \[−8x−14+14=18+14\]
What does: \[-14 + 14 = ?\]
\[18 + 14 = ?\]

Answer 19

@LoveIt

Answer 20

oh 32

Answer 21

Yes, so it would look like this: \[−8x=32\]
Now, divide both sides by -8: \[\frac{ -8x }{ -8 } = \frac{ 32 }{ -8 }\]

Answer 22

What does that equal? ^ @LoveIt

Answer 23

-4

Answer 24

Yes, so the answer is: x=−4

Answer 25

Think of this...
