Using Substitution and Elimination Method

Example 1

Solve the simultaneous equations 2x + 5y = 1, 3x – 2y = 30

Solution

Firstly name the first equation as equation one and the second one equation two

That is; 2x + 5y = 1 …………………………………………………….eqn (1)

           3x – 2y = 30…………………………………………………….eqn (2)

Secondly you Eliminate one of the unknowns by

Multiplying eqn (1) by…
