• On both sides of the equation first subtract six, then divide by three, and finally subtract one.

• On both sides of the equation first divide by 3, then subtract six, and finally subtract one.

• On both sides of the equation first subtract one, then subtract six, and finally divide by three.

If we are given

 $-2\left(x-1\right)+5=-9$ which is the correct way to solve for x? 

• -2(x-1)+5=-9

  -2(x-1)=-14
  x-1=7
  x=8

• -2(x-1)+5=-9
  

  -2(x-1)=-13
  x-1=11
  x=12

Where did i make the first mistake when solving for x?

step(1) -7=-2(x+5)-1
step(2) -6=-2((x+5)
step(3) -4=x+5
step(4) -9=x 

• step 3

• step 1

• step 2

• step 4
