Question statement

Find $x$ in the following equations. Give your answer correct to two decimal places when the answer isn't a whole number.

Give any introductory information the student needs.

			Name	Type	Generated Value

a	list	[ 5, 6, 6 ]
af	integer	4
b	list	[ 8, 5, 9 ]
c	list	[ 11, 11, 9 ]
d	integer	3
f	decimal	dec("1.83")
g	decimal	dec("6.00")

Gap-fill

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

$\simplify{x+{b[0]}={c[0]}}$

$x=$ Unnamed gap

Advice

In part a)

$\simplify{x+{b[0]}={c[0]}}$

On isolating $x$ to one side,

$x= \var{c[0]}-\var{b[0]}$

$x= \var{d}$

In part b)

$\simplify{{a[1]}x={c[1]}}$

Solve for $x$ ,

$x= \frac{\var{c[1]}}{\var{a[1]}}$

$x= \var{f}$

In part c)

$\simplify{{a[2]}/{af}x={c[2]}}$

$x= \frac{\var{c[2]}*\var{af}}{\var{a[2]}}$

$x= \var{g}$
