Question

Could someone show me how to simplify (5m - 2) - (3m - 2n + 5)?

Answer 1

first take out parenthesis as follows:

5m-2-3m+2n-5 now combine like terms

Answer 2

Ivette is right :)

Answer 3

Omg! My mistake it's -2 -5 = -7!

Answer 4

So the correct answer is 2m + 2n -7 I'm so sorry!

Answer 5

Thank you all!

Answer 6

You're welcome! :)

Answer 7

You've all been such a big help.

Answer 8

I'm glad I helped :)

Answer 9

Could someone help me with one more?

Answer 10

Sure, post it!

Answer 11

Okay, simplify: \[(16x ^{4} - 4x ^{3} + 8x - 7) - (5x ^{4} + 4x ^{2} - 8x +12)\]

Answer 12

you have to distribute that - to the 5 4 -8 and 12

Answer 13

11x^4 - 8x^3 + 16 x - 19

Answer 14

It's all adding and subtracting to the like terms! Really easy!

Answer 15

Thanks!

Answer 16

You are welcome!

Answer 17

The way i think about adding like terms is like normal addint
123+341
123
+ 341
464
-----------
as you can see we have hundred, tens and ones. We cant add the tens to the ones or hundreds to tens... you get the idea. They have to be same.

In algebra you have powers
1x^2+2x+3 + 3x^2+4x+1

1x^2+2x+3
+3x^2+4x+1
4x^2+6x+4
I see them as x^2s, xs and constants the one without an x :).
It is like you would see hundreds, tens, and ones


Also when you do it with algebraic like terms there is no carrying over it just stands as is.
Example:
19
+12
31
vs alebra
9x
+2x
11x no carry over
