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`

→ Used by:

Statement
"Unnamed part" → "Gap 0." - Correct answer
"Unnamed part" → "Gap 1." - Correct answer

Parts

Gap-fill
1. Gap Gap 0. Mathematical expression

Gap-fill

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

$x=$ Gap 0.

$y=$ Gap 1.

Input your answers as fractions (use the '/' key) and not as decimals.

Advice

A general method is to make the coefficients of either $x$ or $y$ equal by multiplying one or both equations by a constant.

You can then add or subtract the resulting equations to get an equation in just $x$ or $y$ , which you can solve.

The value of the other variable can be found by substitution into one of the original equations.

For more explanation, look for the relevant resource "Simultaneous Linear Equations" in the Algebra - Equations section of our Maths Study Skills page.
