Simultaneous Linear Equations

At this stage, we already have an idea or two on the steps taken to solve problems involving simultaneous linear equations hence, we go straight to examples to refresh our memory on the steps involved. Now simultaneous equations can be solved using either the substitution method or the elimination method.

Example 1: Solve the simultaneous equation using

1. Substitution method            b. Elimination method

Solution:

1. Substitution method

Make y the subject in equation (1)
