Question 1007197: Solve the system by substitution, if possible. (If the system is inconsistent, enter INCONSISTENT. If the system is dependent, enter a general solution in terms of x or y.)
{3x-y=20
{y=3x-20 Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! From
3x-y=20
y=3x-20
let us substitute the second one into the first equation...
3x - (3x - 20) = 20
20 = 20
This tells us there are an infinite number of solutions.
In fact, these are the very same equation, the same line and a DEPENDENT system where y = 3x - 20.
