Ref to lesson on simultaneous equations
Just felt that it would help to point out the number of equations needed to solve for certain number of unknowns. For example:
2 unknowns x,y will require 2 or more different equations involving x,y so as to solve.
goes on for 3, 4...
Might help the students to pick out enough key points in word problems so as to form the required equations.
Hope it helps
