How do I use elimination to find the solution of the system of equations #y=2x+1# and #2y=4x+2#?
To start, you want to manipulate the equations so that they are in standard form (
To to this, you want all the variable terms on one side, and the constants on the other side. Thus, both equations must be manipulated:
move 2x over to the other side by subtracting 2x from both sides:
Now manipulate the other equation by moving the 4x over to the other side:
You should notice that this equation can be simplified further; all the terms in the equation can be divided by 2.
Hopefully this was of some help and hopefully you've understood this! :)
