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

  1. The solution is a = 5

  2. undo multiplying by -28 by dividing by both sides of the equation by -28 to get a = 5

  3. Check the solution by evaluating the original expression -4(7(5)+5) to verify that it equals -160

  4. undo subtract 20 by adding 20 to both sides of the equations to get -28a = -140

  5. Use distribution to multiply (7a+5) by -4 to get -28a - 20=-160

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

  1. Simplify like terms to get the equation -7x - 3 = 25

  2. undo subtract 3 by adding 3 to both sides of the equations to get -7x = 28

  3. Check the solution by evaluating the original expression -4x -7 - 3x +4 to verify that it equals 25

  4. undo multiplying by -7 by dividing by both sides of the equation by -7 to get x = -4

  5. The solution is x = -4

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. Simplify like terms to get the equation 13k - 6 = 7

  3. Use distribution to multiply (5k-3) by 2 to get 3k+10k-6=7

  4. undo subtract 6 by adding 6 to both sides of the equations to get 13k = 13

  5. The solution is k = 1

  6. Check the solution by evaluating the original expression 3k+2(5k-3) to verify that it equals 7
