Question

-5x+3y+4x-2.

anonymous · Answer

i need help solving it

anonymous · Answer

what is the problem?

anonymous · Answer

i dont no how to simplifly expression

directrix · Answer

If the instructions are to simply the given expression, then:

-5x+3y+4x-2=
-5x + 4x + 3y -2 =
-x +3y -2.

anonymous · Answer

how do u get the answer tho?

anonymous · Answer

-5x+3y+4x-2
-5x+4x=x so, it would equal
x+3y-2 all together

directrix · Answer

-x +3y -2 is the answer.
Here's the work from above:
-5x+3y+4x-2=
-5x + 4x + 3y -2 =
-x +3y -2.
The only thing to do is to combine -5x and 4x into -x.

anonymous · Answer

$$-5x+3y+4x-2$$$$-5x+4x+3y-2$$$$-x+3y-2$$

anonymous · Answer

so it would be -x+3y-2 would be the answer

directrix · Answer

Yes.

anonymous · Answer

ok no this one 4x+5y-y+3x

anonymous · Answer

plz
'

anonymous · Answer

4x + 3x + 5y - y = 7x + 4y

anonymous · Answer

how do u do it

anonymous · Answer

can you explan itplz

directrix · Answer

4x+5y-y+3x.
=========
Look at the expression and eyeball like terms.
4x and 3x are like terms - they have the same "last name" of x
5y and -y are like terms - they have the same "last name" of y

Group the like terms together, combine them according to the operation, and that is called simplification in this problem.

So, 4x+5y-y+3x = 4x + 3x + 5y - y   (note that like terms are together.

Also, note that 4x + 3x = 7x.

Also, note that 5y - y = 5y - 1y = 4y.

Putting all that together,

4x+5y-y+3x = 4x + 3x + 5y - y = 7x + 4y.

7x + 4y is the answer.

one more can u explain 6p+3p+7z-13z

anonymous · Answer

plz

directrix · Answer

With two examples already done, I would like for you to post what you think you should do. In the problem, 6p+3p+7z-13z, the like terms are already together. So, combine them and let's see what we get. Be brave.

anonymous · Answer

so 6p+3p=9p then 7z-13z=20z then the answer is 9p+20z i think?

anonymous · Answer

?

directrix · Answer

6p+3p=9p Yes, this is correct.

Look at 7z-13z again. 7 of something minus 13 of that same something --> would that result in having 20 of that something.

Or, think about it this way, if I owed you $13 and then gave you $5, would you then have $20?

directrix · Answer

* Typo Correction: Or, think about it this way, if I owed you $13 and then gave you $7, would you then have $20?

directrix · Answer

@jojo16  
7z-13z = -6z
-------------------

6p+3p+7z-13z=

9p - 6z  -->
