Given linear equations, I, II and III, a learner is not able to solve III algebraically. The most likely area of difficulty is that the learner has not understood
that two equations can be solved by method of substitution
the method of solving equations using graphs
that both the equations in III can be altered by multiplying with suitable numbers
that two equations can be added or subtracted to solve then
When doing exponents, the work observed in a learner's notebook was as follows

The learner has not understood how to
add exponents and multiply
multiply numbers with same base
