Linear Combination
14x+4y=-2
3x-4y=19
|
3x-4y=19 |
We are going to do a linear combination problem and the first thing that you would need to do is make either the "x"'s or the "y"'s opposite equals, so that they cancel each other out. |
|
3x=19 |
The "y"'s cancel out and you are left with this so now you must add these together. |
|
|
Then, get the variable on one side by itself by divideing "both" sides by 17. |
|
|
Now, "substitute" the "x" back into either on of the original equations. |
|
|
Distribute the "1" to the 3. |
|
|
Combine like terms. |
|
|
A variable can't have a coefficent so you must divide both sides by -4. |
|
|
Now, you must put the "x" and "y" into a coordinate pair. |
|
|
This is the final answer. |

(1,-4)
