How To Do Basic Algebra - III

Education : Maths

Often to solve an equation, you will need to take terms out of brackets - or 'multiply out' brackets. For instance:

2(3x - 7)

The key is to remember that you must apply what is outside the bracket to EVERYTHING in the bracket.

This re-writes, therefore, to:
2 times 3x minus 2 times 7

or 6x - 14
