Tell whether the system has one solution, infinitely many solutions, or no solution.
1. y = 3x − 7 2. y − 3x = − 2 3. y = −3x + 12
y − 2x = − 6 y = 3x + 5
please help cant figure these out!!

anonymous · Answer

you have 5 equations and only three of them are numbered. this is confusing, clarify which ones are part of the system of equations

anonymous · Answer

oh my bad hold on

anonymous · Answer

actually I think I have the answer

anonymous · Answer

in your first one stating that y=3x-7:
use 3x-7 in place of y in your other equations and you will quickly see the correct answer.

anonymous · Answer

Their are only three the frist one is  1. y = 3x − 7
                                                               y − 2x = − 6

|dw:1387387187972:dw||dw:1387387462027:dw|
plugging these values back into the second equation to see if it is true
