Question

Which of the following equations have the same solution? Solve all three equations separately, and explain each step.
I. 3x + 2 = 5x – 6
II. 2x – 2 = 8
III. the quantity of x plus 1, divided by 5 equals the quantity of 2x minus 2, divided by 6

Answer 1

I need a little help :)

Answer 2

rearrange the first equation to the same form as the second and see what you get

Answer 3

so would it be

3x - 5x = 2 + 6

Answer 4

have no clue

Answer 5

@invinceble if you have no clue it is best not to say it

Answer 6

is that correct @cwrw238

Answer 7

no

Answer 8

subtract 3x from both sides
then add 6 to both sides

Answer 9

@cwrw238 is right. You need to subract from both sides

Answer 10

subtract*

Answer 11

Hmm so that would be like 3x + 2 = 5x – 6
-3 -3
Is that ok ?

Answer 12

no subtract 3x not 3

Answer 13

Math can be so confusing sometimes XD

Answer 14

Oh
3x + 2 = 5x – 6
-3x -3x

Answer 15

yes it can @PaulaLovesSchool13

Answer 16

3x + 2 = 5x - 6
- 3x -3x

2 = 2x - 6
+6 + 6

8 = 2x


what what is x?

Answer 17

x = 4

Answer 18

Good!

Answer 19

ok now solve the second equation

Answer 20

2x – 2 = 8
+ 2 +2
2x = 10
x = 5
Correct ?

Answer 21

right

Answer 22

Yes, that should be right. Good job Carolina :)

Answer 23

Yay
