Solving Simultaneous Equations
The below QuickQuestion Interface © generates random questions on solving simultaneous equations.
Choose which type of problems you want (no multiplying, one multiplied or both multiplied, or choose Random for a mixed selection.
Decide on the signs within the equations.
Decide whether to allow negative answers and fractional answers.
Choose to use x and y, or random letters for each question.
Finally decide on the maximum value for numbers as answers.
When typing answers, you must include the letter with the relevant answer, and separate them with a comma (the order does not matter). So "x=3,y=2" and "y=2,x=3" are both acceptable.
Use the buttons to create random questions and show the answers.
There is a 10QQI version of this activity.

Ideas for Teachers
The QQI activities are a great way to get all students working. Put random questions on the board, and then get students to answer them on mini-whiteboards. Once all students have answered, and held up their solutions (with working), reveal the answer to see if they were right. Discuss any misconceptions from the working they have shown, or if they have all got it correct, move on to another question (changing the options to make if more difficult if necessary).
