For what ordered pair (a, b) are there infinite solutions (x, y) to the system
4x+ay=-8,
2x+y=b-2x
+2668 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?
