Question

Help: I need help with Linear Equations:

5(x-3)+4x-1=2x+3(x-2)

Answer 1

Find x?

Answer 2

Yes

Answer 3

Distribute 5, also 3 into the respective bracket, can you?

Answer 4

Ill show you what i have and can you tell me where i went wrong?

Answer 5

This is the original question:
5(x-3)+4x-1=2x+3(x-2)

This is what i got next:
5x-15+4x-1=2x+3x-6

Then i got this:
9x-16=5x-6

Then i got this:
9x+5x=-22

Is this right?

Answer 6

That last one is wrong, you need to flip the signs when you switch sides...

Answer 7

So what would i flip? -16 to 16 ?

Answer 8

What I mean is if you bring something from one side of the equals to the other then you need to change the sign of that something.....

Answer 9

Or, the way they teach you to do it is like:

9x-16=5x-6 now subtract 5x from both sides ->
9x-16 -5x = 5x - 6 -5x
4x -16 v= -6 now add 16 to both sides etc etc

Answer 10

Comes to the same thing...

Answer 11

so would your answer be x=2.5? cause you divide the 10 by 4?

Answer 12

4x -16 v= -6
4x = 10 Now divide both sides by 4
x = 5/2 (or 2.5 if you like)

Answer 13

Okay thank you so much!
