9
5
3
2

Answer 1

5(2x − 6)
Distribute

Answer 2

well i guess i should start off by saying i got 2 as my asnwer

Answer 3

Thats correct

Answer 4

oh ok thanks :D

Answer 5

5(2x−6)+20=10
Step 1
5(2x−6)+20=10
Simplify
5(2x−6)+20=10
(5)(2x)+(5)(−6)+20=10(Distribute)
10x+−30+20=10
(10x)+(−30+20)=10(Combine Like Terms)
10x+−10=10
10x−10=10
Step 2: Add 10 to both sides.
10x−10+10=10+10
10x=20
Step 3: Divide both sides by 10.
10x
10
=
20/10
x=2

Answer 6

wow I would have subtracted 20 as the 1st step

\[5(2x - 6) + 20 -20 = 10 -20 ~~~so ~~~~ 5(2x -6) = -10\]

then divide both sides by 5

\[\frac{5(2x -6)}{5} = \frac{-10}{5} ~~~~so~~~~ 2x - 6 = -2\]

next add 6 to both sides of the equation

\[2x - 6 + 6 = -2 + 6~~~~or~~~~2x = 4\]

now solve for x

it saves a few steps

Answer 7

x = 2
