i need to know how to simplify an equation in math!?

Question

i want to know how to simplify this (2x+5y-6)+(3x-4y+12) and possibly (x+5))+(2y-6)-(3x-2y) THANKS in advance

Answer 1

(x+5))+(2y-6)-(3x-2y) do the x's first
so you have x+5+2y-6-3x-2y,

1. (remember that when you have only a variable with no number, there's a one in front of it) so you have 1x-3x= (-2x)

2. (Now I'll do all the constants, the numbers without variables attatched to them) 5-6= (-1)

3. (Now the y's) 2y-(-2y)=4y (remeber here that there are 2 negative signs before the last 2, so 2 negatives make a positive)

-2x-1+4y I don't know what your teacher prefers, my teacher liked us to list the variables in alphabetical order and then the constants.

so, my teacher would want me to write this as -2x+4y-1 (both ways still give you the right answer though :) )

Try the second one yourself, I think you will do fine.

Answer 2

like everyone else said the answer to the first equation is 5x+y+6.

Because look you have (2x+5y-6) +(3x-4y+12) you break it down like this since you have like variables you take 2x+3x= 5x

then you have 5y-4y=1y or "y" then you have -6+12= 6. so your answer is

"5x+y+6"

I'm working on the same type of math in school..and figuring out your problem actually made me understand it a little bit better...Hope you understand now.

Answer 3

First, you add like terms. So, since both 2x and 3x have x's on them, you add those together. Do the same for the other terms. (5y-4y and -6+12)

You should get 5x+y+6.

Simply do the other problem the same way.

Answer 4

number one: (2x + 5y - 6) + (3x - 4y + 12)
= 2x + 5y - 6 + 3x - 4y + 12
= 2x + 3x + 5y - 4y - 6 + 12
= 5x + y + 6

number two: (x + 5) + (2y - 6) - (3x - 2y)
= x + 5 + 2y - 6 - 3x + 2y
= x - 3x + 2y + 2y + 5 - 6
= -2x + 4y - 1


im doing my math homwork rite now too :)

Answer 5

You just need to take each part of the equation separately. Take the x parts and add them together and then the y parts and so on. The answer for the 1st equation would be: 5x+y+6

And the answer for the second equation would be: -2x+4y-1

Always remember the signs when adding, subtracting, multiplying etc. + and + make +
- and - make +
- and + make -

Answer 6

1. 5x + y + 6

2. -2x - 1 + 4y

Answer 7

I have sent over some sites that have help with simplication. I don't usually like to give answers, however I the sites should make you a master and will help with all your problems. Good Luck!

Answer 8

add the x numbers together
add the y numbers together and
add the whole numbers together
(5x 1y 6) I think
