If you were solving a system of equations and you came to a statement like 4 = 4, what do you know about the system?

Question

amistre64 · Answer

when does 4=4?

anonymous · Answer

Umm, I'm not sure..

amistre64 · Answer

4=4 is a true statement and is ALWAYS true.

this should bring to mind that the system ALWAYS shares common points, so they are congruent systems.

amistre64 · Answer

congruent is prolly not technically correct ... but it means they are the same system regardless.

prolly

anonymous · Answer

Solve the following system and show all of your work.
3y − 2x = 11
  y + 2x = 9

I got : x=2, y=5

amistre64 · Answer

you didnt show your work ... but as a dbl chk:

3y - 2x = 11
 5      2
-----------
15 - 4 = 11 is true


y + 2x = 9
5     2
----------
5 + 4 = 9 is true
