Difference

The x terms in both equations are the same positive integer and the simultaneous equations are solved by subtracting the bottom equation from the top equation.

Addition

The x terms in both equations are the same magnitude, but the top x term is positive, and the bottom x term is negative. The simultaneous equations are solved by adding the top and bottom equations.

Balancing

The simultaneous equations are solved by balancing either the y terms or the x terms and subtracting. Both methods are shown when the 'Show answer' button is clicked.
