This starter has scored a mean of 2.9 out of 5 based on 15 votes.
There are of course no end of correct answers and here are some examples.
There is at least one mistake. Can you find the errors when x=5 and y=2?
|x + y = 7||x - y = 3||y - x = -3|
|2x + 3y = 16||5x - 2y = 26||4y - x = 9|
|xy - 10 = 7||180 - 2x + y = 172||20x - 3xy = 70|
|x2 + y = 27||10x - y2 = 46||y2 - x2 = -21|
|x2y + 13 = 76||x2y2 - 2x = 90||x2y3 = 200|
|x! + y = 122||5(x + y) = 35||5y ÷ x = 2|

Maths is Important!
"Mathematics equips pupils with uniquely powerful ways to describe, analyse and change the world. It can stimulate moments of pleasure and wonder for all pupils when they solve a problem for the first time, discover a more elegant solution, or notice hidden connections. ...
Mathematics is a creative discipline. The language of mathematics is international. The subject transcends cultural boundaries and its importance is universally recognised. Mathematics has developed over time as a means of solving problems and also for its own sake."
