Question 999373: solve the following system by solving one of the equations for x or y and then using the subsitution methon
y=4x+7
y=4x-3 Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! From
y=4x+7
y=4x-3
we can substitute the first value for y in the second equation...
4x + 7 = 4x - 3
Now subtract 4x from both sides...
7 = -3
Now, ask yourself, when does 7 = -3???
Never!
Thus there is no solution here.
