Select TWO possible ways for you to start solving this equation:

10x+20=5(x−1)

• Divide both sides of the equation by 5 to get

  2x+4=x-1

• Divide 20 on both sides of the equation to get

  50x+1=4(x−1)

• Subtract 20 from both sides of the equation to get

  10x=5(x-21)

• Subtract 5 from both sides of the equation to get

  10x+15=x-1

• Distribute 5 on the right side of the equation to get

  10x+20=5x−5
