Answer:
A: one solution
B: no solution
C: infinitely many solutions
Step-by-step explanation:
for a, the solution is (-3, -1)
for b, the end equation is 0=24 which is not accurate, this makes it no solution.
for c, you rearrange it.
4x+y=-6
then it is 8x+2y=-12 over 4x+y=-6
multiply the bottom by -2.
-8x - 2y = 12
everything cancels out,
0 = 0 is the end solution.
0 = 0 means their is an infinite amount of solutions.
hope this helps :)
