QTB – MAY 2017 – L1 – SA – Q3 – Mathematics.

A multiple-choice question assessing knowledge of simultaneous equations and variable relations.

Question

Which of the following is NOT TRUE about simultaneous equations?

A. The number of variables must be equal to the number of equations.
B. Where two lines intersect, the values of the variables at that point must satisfy the equations.
C. The simultaneous equations must be satisfied by values of the variables as well as their reciprocals.
D. Their solution involves finding the values of the variables which are true to all the simultaneous equations.
E. The result of adding the equations or subtracting one equation from the other will be satisfied by the values of the variables.
