Question

Part 1:
If you were solving a system of equations and you came to a statement like 4 = 4, what do you know about the system?
Part 2:
Solve the following system and show all of your work.
3y − 2x = 11
  y + 2x = 9

anonymous · Answer

y+2x=9
   -2x  -2x
y=9-2x
replace y in the first equation for 9-2x 
3(9-2x) -2x=11
27-6x-2x=11
27-8x=11
    +8x  +8x
 27= 11+8x
-11 -11
16=8x
divide both sides by 8 
x=2
replace x with 2 in the equation y+2x=9
y=5
