Question

Determine if the solution set for the system of equations shown is the empty set, contains one point or is infinite.
x - y = 5
2x + y = 1

Answer 1

If you get at the end something like 8=7 that means it's an empty set, if you get x=some number and y=some number then it contains one point and if you get something like 0=0 then it's an infinite set.
