equations involving algebraic fractions

the idea for these tasks is from a question in Tony Gardiner's 'mathematical puzzling' book (1987)













the questions can be solved by trial and improvement but are intended to encourage an application of how to proceed with fractions and other techniques

'wigwam' is a visual cue for the procedure of adding/subtracting fractions
(sometimes called other things but 'wigwam' is heaps better)
