Put these operations in the order by which you perform them to simplify an expression. (first to last)

  1. multiplication
  2. exponents
  3. parentheses ( )
  4. addition
  5. division
  6. subtraction
Question 11
11.

To solve an equation we need to undo operations to isolate a variable. So, we need to undo PEMDAS. This means we need to work in a different order.

Put these operations in the order by which you perform them to solve an equation. (first to last)

  1. addition and subtraction (outside parentheses)
  2. multiplication and division
  3. parentheses ( )

Use your notes from page 5 to list the 3 steps you use to solve multi-step equations.

1._______
2._______
3._______
Question 39
39.

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


  1. The solution is a = 5
  2. Use distribution to multiply (7a+5) by -4 to get -28a - 20
  3. undo subtract 20 by adding 20 to both sides of the equations to get -28a = -140
  4. Check the solution by evaluating the original expression -4(7a+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
Question 40

Question 41
41.

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


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

Question 43
43.

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



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