How do you solve the system of equations #2x + y = 30# and #4x + 2y = 60#?
1 Answer
An infinite number of solutions exist.
Explanation:
We can start by using substitution.
The first equation solves easily for
This equals "
But wait- the "
So that's the answer: There are an infinite number of solutions.
Also, you can try dividing both sides of the second equation by
a given system of equations represent the same line, it is called a dependent system.
