yes

jdoe0001 · Answer

if 2 equations "simplify" to exactly the same thing
that means that they're really both exactly the same
but in disguise

and when the system of equations have 2 who "simplify" to the same equation, they have infinite solutions

for example    say 

  2x+3 = 5    and
 4x-7 = 11

notice the 2nd one 
4x -7 = 11  =>   4x =4  =>   $\bf x = 1$

notice the 1st one
  2x +3 = 5  => 2x = 2  => $\bf x = 1$

jdoe0001 · Answer

they look different, but they simplify to the "same", so they're really the same in disguise

so..... any ideas on what of your choices is really  "4(3x-5) + 6"   in disguise?

jdoe0001 · Answer

wel.... actaull above should have been   4x +7 = 11  anyhow   

4x + 7 = 11 => 4x = 4 = > $\bf x =1$

can you simplify  "4(3x-5) + 6" ?   what would it give  you?
