6x + 3x - 2y + 4y Help!!?

Question

YOu do not have to tell me the answers, just help me i with the steps in getting it. Thank YOu so much! :]

Answer 1

OK

Add the x's and add the y's

6x +3x = 9x
-2y + 4y = 2y

9x + 2y

Hope that helps!

Answer 2

6x + 3x -2y +4y = 0

combine the "likes"

9x + 2y = 0

Solve for X

9x = -2y (this is your new short equation for next time, btw)
Divide each side by 9 to single out x.
x = -2y/9

Now that you know what X represents, Plug X in equation:

9x = -2y
9(-2y/9) = -2y
The 9s cancle each other out leaving:
-2y = -2y
Y = 1

Plug Y into X to find real X:

X = -2y/9
X = -2(1)/9
X = -2/9
_________________
Answer:
Y = 1
X = -2/9

Check:
Plug both X & Y into the equation. A true statements = correct answers.
9x + 2y =0
9(-2/9) + 2(1) = 0
-2 + 2 = 0
0 = 0

Answer 3

add the numbers with the same variables

add 6x & 3x = 9x
add - 2y & 4y = 2y

ans:
9x + 2y

Answer 4

Combine the like terms. 6x + 3x should be 9x, and -2y + 4y should be 2y. So the answer should be:

6x + 3x - 2y + 4y = 9x + 2

Answer 5

just add the like terms together

6x + 3x = 9x
-2y + 4y = 2y

so the answer is 9x + 2y

Answer 6

Firstly, 6x + 3X = 9x
Then, -2y + 4y = 2y

Finally, 9x +2y

Answer 7

First lets simplify the equation and combine like terms:

eqn.1) 9x + 2y = 0

We want the equation to equal "y" so we take it to the other side:

eqn.2) 9x = -2y

Now lets move the negative 2 over so all were left with is a "y" on the one side.

9x/-2 = y

And that's your answer. Hope that helps.

Answer 8

We get the result = 9x + 2y by grouping like terms

Answer 9

First you add 6x+3X, then that would equal 9X. Then you add -2y plus 4y, and that equals 2Y
9X+2Y

Answer 10

9x+2y
