By Direct comparison of the left hand side with the right hand side
Divide both sides by x in
Make A the subject of formula
Substitute 1 - B for A in
Subtract 1 from both sides
Divide both sides by -3
Substitute -2 for B in
Hence;
Solving
Because we're dealing with an absolute function; the possible expressions that can be derived from the above expression are;
and
Solving
Make t the subject of formula
Multiply both sides by -1
Solving
Make t the subject of formula
Divide both sides by -3
<em>Hence, the values of t are: -3, -1</em>
