Description

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

Generated value: `integer`

Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

Consider the equation:

$\simplify{x^{{n1}}*y + {n2}*y*x} = \simplify{{n3}*y} + \var{n4}$

Re-arrange this equation to make $y$ the subject:

$y =$ Unnamed gap

Advice

Here, we first have to collect all terms involving $y$ on the same side. Hence, we get:

$\simplify{x^{{n1}}*y+{n2}*y*x - {n3}*y} = \var{n4}$

We then spot that $y$ appears exactly once in each term on the left, so factorise:

$y(\simplify{x^{{n1}} + {n2}*x - {n3}}) = \var{n4}$

and simple division gives the answer.

Give a worked solution to the whole question.
