Solve equations given below using elimination method: x + y = 3 -3x + 2y = 1

x= 1; y=2

Step-by-step explanation:

x+y=3;

-3x+2y=1

To use elimination we must eliminate one of the variables. To do eliminate the x multiply the top equation by 3.

3x+3y=9

-3x+2y=1

Now add the 2 equations to eliminate

5y=10

y=2

Plugin y into another equation.

x+2=3

  -2=-2

x=1

its a straight line parallel to the time axis
