The last equation in the previous section ended up as:

3*x* = 18

The expression 3*x* represents the value of *x* multiplied by three. The aim of the exercise is to find the value of *x*. Again, we need to transform both sides of the equation so that we are left with the unknown on one side of the equation. Here, we divide both sides by 3:

3*x*/3 = 18/3

*x* = 18/3 = 6

The short cut method is simply to move the multiplier to the other side of the equals sign, and turn it into a divisor, thus:

3*x* = 18

*x* = 18/3

*x* = 6

Similarly, a divisor becomes a multiplier when it is moved across to the other side of the equation:

*x*/7 = 5

*x* = 7 × 5 = 35
