5x+4y=6 2x+-4y=8 |
The objective of the elimination method is to eliminate one of the variables so that you can solve for the other variable. You can multiply an equation by a certain number so that it can be eliminated, but luckily I have made this equation easy in that you do not need to multiply any side of the equation to eliminate it. |
5x+4y=6 |
Add the two equation together to eliminate the y variable |
x=2 |
Divide both sides by 7 |
5(2)+4y=6 |
Plug the value of x back into the original equation to solve for y. |
10+4y=6 |
Multiply 5 by 2 |
4y=-4 |
Subtract both sides by ten. |
x=2 y=-1 >>>>>(2,-1) |
Divide both side by 4 and you have your y value . So now you have both your x and y values . |
