Use elimination to solve the system of equations given by 3x+4y=5 and 21x+28y=35
Your "two" equations are "one" equation!!. If you multiply the 1st one by 7, you get the 2nd equation.
Um that's not what I needed....but thx?
Note to the questioner.....the "Guest" is correct.......these are the same equations....thus.....the "system" will have infinite solutions for x and y
