This document provides worked solutions for 3 algebra examples. The first example shows how to isolate the variable x when 2x = 6 by dividing both sides by 2, finding that x = 3. The second example solves the equation x + 6 = 9 by subtracting 6 from both sides, also getting x = 3. The third example indicates there will be harder questions solved using the same isolation of variable techniques shown in examples 1 and 2.

1. Algebra Worked Solutions
Example 1:
Basic Single Step Algebra
2x = 6 1. Get x on its own.
This is the same as 2 × ___ = 6
x=
6
2
2. Find the value of x.
i.e. 6 ÷ 2=x
x = 3
Example 1b:
x + 6 = 9
x = 9 − 6
x = 3
