Watch the video on solving a simple equation.
Points to remember:
- When asked to solve an equation, your goal is to find the value for the variable (x)
- You want to isolate (get it by itself on one side of the equation) the variable
- Each step you take must preserve equality (meaning what you do to one side of the equation, you must do the same to the other side)
- Verify means to check that when you substitute your solution back into the equation, both sides of the equation are equal
In your text book, you can try p.331 Q. 5, 6 (just solve don't worry about the model), Q.8, Q.11 Q.12 The solutions are on p. 520.
