For what ordered pair (a, b) are there infinite solutions (x, y) to the system
4x+ay=-8,
2x+y=b-2x
+2666 Add 2x to both sides of the second equation: \(4x + y = b\)
The first equation is \(4x + ay = -8\)
Because they have a ratio of 1, the 2 equations must be identical.
So, what values of a and b will make the second equation identical to the first equation?
