Endless Simultaneous Equation generator

This macro-enabled Excel spreadsheet contains three styles of simultaneous equation questions suitable for UK Key Stage 3 and GCSE sets or the equivalent. For each style, the ‘Generate questions’ button generates ten questions at a time. The solution to each question can be revealed individually by clicking the appropriate ‘Show answer’ button.

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.

NOTE: for this spreadsheet to work correctly, the copy of Excel in which it is running must allow macros to execute, and ‘Enable Content’ must be clicked when the spreadsheet is opened.
