Question

use the substitution method to solve the system of linear equations 
x-y=1
5x-5y=5
(a) there is one solution (ordered pair)
(b)there are infidelity many solutions 
(c) there are no solutions

Hint: multiply both sides of equation 1 by 5 and then compare that result with equation #2.

vortish · Answer

if we do that then we come up with same as equation 2

anonymous · Answer

Yes, and so we have an infinite # of solutions.

So, letter b.  Your answer key is supposed to read infinitely, not "infidelity".  :-)
