1.2 Algebra - Transposition & Linear Equations Flashcards
What are the 4 rules of transpotion?
- Remove Fractions
- Remove Brackets
- Move added/subtracted terms
- Divide by the number next to the letter
Main princple when changing sides in transposition?
change sides = change signs
in linear equations, what is the constants?
the numbers that remain at a constant and don’t change
in linear equations, what is the unknown (variable)?
the number that you are seeking to find the value of.
in linear equations, what must be done throughout?
operations must be performed on both sides
in linear equations, what do you do when the unknown is on both sides?
aim to get the unknown on one side, and the constant on the other.
in linear equations that have fractions in them, what do you do?
multiply both sides by the denominator
in linear equiations, if there is fractions on both sides, what should you do?
rewrite it as necessary, and carry out cross multiplcation to remove the fractions.
