  • First you simplify the equation and add +2x to both sides of the equation
  • -3(2x+5)=15
  • Jake, would you solve this equation for the class ?
  • 
  • 3(x+4)=-2x-18
  • Chase, What is the first step to solving this equation ?
  • Yes
  • -3(2x+5)=15
  • 3
  • -6x +-15=15
  • -6
  • ___
  • 
  • x=-5
  • -6
  • ___
  • +15
  • 3
  • 
  • -6x=30
  • +15
  • First you subtract -3 from both sides of the equation, then add 15 to both sides
  • -3(2x+5)=15
  • 3
  • -6
  • -6x +-15=15
  • ___
  • ___
  • -6
  • +15
  • -6x=30
  • 3
  • +15
  • x = -5
  • Subtract -6 and your answer will be x = -5
  • +2x
  • 3x+12=-2x-18
  • +2x
  • Then you subtract 12 from both sides of the equation 
  • 
  • -12
  • 5x+12=-18
  • 5x=-30
  • -12
  • To get your answer you divide 5 to get rid of 5 and whatever you do to one side you do to the other
  • 
  • 5
  • ____
  • x=-6
  • 5x=-30
  • ____
  • 5
