3x+5 = 10x - 7 ?

Good now just solve for x

  • gudetamas
7x = -12
pooja195
  • pooja195
How did you get that?
gudetamas
  • gudetamas
i subtracted 3 by 10 and got 7, and subtracted 5 by -7 and got -12
pooja195
  • pooja195
Subtract 7x from both sides. 5x−12−7x=7x−61−7x What do you get?

2x-68 and it simplifies to 17
pooja195
  • pooja195
Hmm still not correct lets do it together :) 5x−7=7x−61 <---given Ok we want to find the value of x lets start by subtract 7x from both sides this way we have our x's on one side 5-7=?

-2
pooja195
  • pooja195
Good Now we have −2x−7=−61 add 7 to both sides this way we have x's on one side plain numbers on the other -61+7=?
gudetamas
  • gudetamas
-54
pooja195
  • pooja195
−2x=−54 good last step! No we need to divide both sides by -2 to isolate the x -2/-2=1 so just x x= -54/-2 -54/-2=?
