replace y in first equation by 2nd one |dw:1433538776999:dw| after that simple algebra solve for c
Nnesha
  • Nnesha
x* not c
DJBreezy
  • DJBreezy
i personally think the answer is C.

  • anonymous
no
Nnesha
  • Nnesha
how did you get C ?
DJBreezy

^^^^^ tried the question u gave me already..
Nnesha
  • Nnesha
C is not correct try again show ur work plz
DJBreezy
  • DJBreezy
answer chack.....B
Nnesha
  • Nnesha
is that a educated guess or you solved it ?
DJBreezy
  • DJBreezy
Educated guess....it was between c and B
Nnesha
  • Nnesha
how about to solve it instead guessing \[\huge\rm -x-2=4x+3\] solve for x or to check an answer replace x and y by order pair if both sides are equal then that order pair is ur answer
DJBreezy
  • DJBreezy
X= -1 @Nnesha
Nnesha
  • Nnesha
yes right \[\huge\rm -(-1)-2=4(-1)+3\] replace x by -1 solve both sides if both sides are equal then your answer is right :-)

  • DJBreezy
idk how to do this part..
DJBreezy
  • DJBreezy
i get confused here
Nnesha
  • Nnesha
yes right \[\huge\rm -(-1)-2=4(-1)+3\] solve left side -1 times -1= ?? and then add -2
DJBreezy
  • DJBreezy
Oh its B
Nnesha
  • Nnesha
my questions is both sides are equal or not ? if both sides are equal then yes if both sides are not equal then no yes right \[\huge\rm -(-1)-2=4(-1)+3\]
