Answer 3

I'll have a go at solving this. The distributive property can be used on the 3(x-y) portion. If you distribute the 3 it will create 3x-3y instead of 3(x-y)

Answer 4

Then you combine like terms. Do you need help with the combining like terms or can you do that?

Answer 5

Could you?

Answer 6

I could explain it to the best of my ability. All our X values can be combined. All the Y values can be combined. But we Can't combine X and Y. So for example the X values are:

3x 3x and -4x so our equation to solve this is

3x+3x-4x. Combined we have 2x. Can you do this for the Y values or is it still unclear?

Answer 7

it's still unclear. sorry!

Answer 8

That's completely okay! So our Y values are 4y and -3y. We can basically ignore our y for now and work with the numbers. It's elementary solving at this point. 4-3=1. we have 1y or just y. Your simplified equation becomes 2x+y!!!

Answer 9

So 2x+y is the simplified version of this problem?
Thank you! your the best!

Answer 10

Correct! Glad I could help you!!

Answer 11

:)

Answer 12

3 x + 4 y + 3 x - 3 y - 4 x = y - 4 x ,
3(x-y) = 3x - 3y
3x - 3x = 0
4y - 3y = y
-4 x = -4x
final equation : -4x + y

Answer 13

thanks @Ogzii YOUR THE BEST!!!!! ;p

Answer 14

@Ogzii could you please let me know the number property used?

Answer 15

@Ogzii Do you mind explaining? I don't see where the -3x comes from.

Answer 16

i guess i was wrong its , y + 2x
