did you solve for x or did you apply substitution method ?

I worked backwards
tiff9702
  • tiff9702
I did \[-45+9 \] and then i did\[-6\times6\]
Nnesha
  • Nnesha
to check ur answer substitute x for 6\[-6(6)-9=-45\] if both sides are equal then yes 6 is the answer if both sides are not equal then no
Nnesha
  • Nnesha
first step is right add 9 both sides but why did you multiply by 6?
tiff9702
  • tiff9702
Both times I got 36 so I assumed if I added 9 to \[-6\times6\] i would get -45
Nnesha
  • Nnesha
alright first step add 9 both sides |dw:1441036121395:dw| now divide both sides by -
Nnesha
  • Nnesha
yes right
Nnesha
  • Nnesha
-6 times 6=-36 -36-9 = -45 both sides areequal good to go!
