Simple equations and inequalities

# Solving equations (continued)

Have a look at these examples:

## Example 1

Solve

With this type of equation put all the x terms on the left hand side.

If we 'take away' the x term from the right hand side, we must do exactly the same thing to the left hand side to keep the equation balanced.

Weighing Balance ()

So

Therefore is the solution.

## Example 2

Solve

Put all the terms on the left.

So, take away from the right hand side and also away from the left hand side (to keep the equation balanced).

Weighing Balance ( = )

So

Therefore is the solution.

## Example 3

Solve

Weighing Balance ( = )

(because )

Therefore is the solution.
