Solving Multi-Step Equations

Required
3

When solving two-step equations, always start with the __________.

Required

What should I do FIRST to solve this problem?
3x + 5 = -16

Required

What should I do FIRST to solve this problem?
-7 + 5f = 23

Required

What are the steps I need to solve this problem?
2x + 5 = 21

Required
10

Put the steps in the correct order to solve this multistep equation.


  1. Use distribution to multiply (7a+5) by -4 to get -28a - 20=-160
  2. undo subtract 20 by adding 20 to both sides of the equations to get -28a = -140
  3. The solution is a = 5
  4. Check the solution by evaluating the original expression -4(7(5)+5) to verify that it equals -160
  5. undo multiplying by -28 by dividing by both sides of the equation by -28 to get a = 5

Solve this multi-step equation. Show your work (SYW)

Required
10

Put the steps in the correct order to solve this multistep equation.


  1. The solution is x = -4
  2. Simplify like terms to get the equation -7x - 3 = 25
  3. undo multiplying by -7 by dividing by both sides of the equation by -7 to get x = -4
  4. undo subtract 3 by adding 3 to both sides of the equations to get -7x = 28
  5. Check the solution by evaluating the original expression -4x -7 - 3x +4 to verify that it equals 25

Required
12

Put the steps in the correct order to solve this multistep equation.



  1. undo multiplying by 13 by dividing by both sides of the equation by 13 to get k = 1
  2. Use distribution to multiply (5k-3) by 2 to get 3k+10k-6=7
  3. The solution is k = 1
  4. Check the solution by evaluating the original expression 3k+2(5k-3) to verify that it equals 7
  5. undo subtract 6 by adding 6 to both sides of the equations to get 13k = 13
  6. Simplify like terms to get the equation 13k - 6 = 7
