Question

How many solutions does the following system have:  y=12?  Why?

anonymous · Answer

where is the system?

anonymous · Answer

Trying to solve a system of linear equations using substitution.

anonymous · Answer

yes but where is the system? the equations?

anonymous · Answer

Sorry, I meant to say the RESULT is y=12 for a system of unknown linear equations using substitution.  How many solutions does the system have?

unklerhaukus · Answer

y=12 
is one solution 
if there are no other solutions
 then there is only one solution

anonymous · Answer

two variable equations? im not sure i understand the question

anonymous · Answer

right unklerhaukus  is right

anonymous · Answer

i just got confused for a sec

anonymous · Answer

Thanks to both of you.  That makes sense.

anonymous · Answer

If the result of a system of linear equations is 8=8, why are the number of solutions infinite?

anonymous · Answer

because you know that the variables canceled themselves out such as 
y = 2x
2x + 8 = y + 8
8 = 8
you can put in any number for y or x (but not both) that you want and it will always be true, you cant do both because y = 2x therefore you cant do y = 10 and x = 8
