Solving Equations Containing Parenthesis
2
Steps
Get rid the parenthesis by using the Distributive Property
Simplify
Add or Subtract
Divide or Multiply
3
Example;
2 (y + 6) = 18
First multiply 2 times y
Then multiply 2 times 6
Is there any thing we need to simplify? (CLT)
Solve for y
4
Multiple Choice
What is the first step to solving this equation?
3 (x + 3) = 18
add 3 and x
multiply 3 times x
5
Multiple Choice
What is the next step in solving this equation?
3 (x + 3) = 18
add 3 and 3
multiply 3 times 3
6
Multiple Choice
Now you have;
3x + 3 =18
What do I do next?
subtract 3x
subtract 3 from both sides
add 3 and 3x
7
Multiple Choice
Now I have 3x=15
What is my last step?
subtract 3 from both sides
multiply 3 from both sides
divide by 3 on both sides
8
Multiple Choice
Complete the first step in this equation (the Distributive Property)
5 (x - 2) = 20
5x + 10 = 20
5x - 10 = 20
5x + 7 = 20
9
Multiple Choice
What do I do next?
5x - 10 = 20
(hint-get rid of the "third wheel" keep the happy couple together)
subtract 5 on both sides
minus 5 on both sides
add 10 on both sides
minus 10 on both sides
10
Multiple Choice
What is the last step?
5x=30
(when a number and a letter are right next to each other it means multiply, what is the inverse of multiply?)
minus 5 on both sides
add 5 on both sides
multiply by 5 on both sides
divide by 5 on both sides
