  • anonymous
21x-14=20x-13
anonymous
  • anonymous
right
gabbyalicorn
  • gabbyalicorn
contradiction?
anonymous
  • anonymous
no watch
anonymous
  • anonymous
21x - 14 = 20x -13 21x -1 =20x x-1=0 x=1 it is what
gabbyalicorn
  • gabbyalicorn
I dont know i still think its contradiction

3x+2(x-10) =5(x-4)
anonymous
  • anonymous
so that would be 3x+2x-20 =5x-20 then what do you do
anonymous
  • anonymous
@gabbyalicorn
gabbyalicorn
  • gabbyalicorn
find like terms?
anonymous
  • anonymous
yes
anonymous
  • anonymous
