The value of x is -5 and the steps taken are:

  • Collect the like terms
  • Subtraction property of equality
  • Division property of equality

Given the equation solved by Marlena

2x + 5 =  - 10 - x

Step 1: Collect the like terms

2x + x + 5= -10

3x + 5 = -10

Step 2: Subtract 5 from both sides of the equation (Subtraction property of equality)

3x + 5 - 5 = -10 - 5

3x = -15

Step 3: Divide both sides by 3 (Division property of equality)

3x/3 = -15/3

x = -5

Hence the value of x is -5 and the steps taken are:

  • Collect the like terms
  • Subtraction property of equality
  • Division property of equality
