Gap-fill

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

$\var{a}x+\var{b}=\var{c}$

$x=$ Unnamed gap.

Advice

Part a)

Given $\var{a}x+\var{b}=\var{c}$ , we can start by subtracting $\var{b}$ from both sides to get $\var{a}x = \simplify{{c-b}}$ .

Dividing both sides by $\var{a}$ gives us $x= \simplify {{c-b}/{a}}$

Part b)

We could start by subtracting $\var{d}$ from both sides to get $-\var{f}y = \simplify{{g-d}}$ .

Or we could first add $\var{f}y$ to both sides to get $\var{d} = \var{g} + \var{f}y$ . This avoids needing to divide by a negative number.

Either way we should end up with $y= \dfrac{\simplify{{d- g}}}{\var{f}}= \simplify{{d-g}/{f}}$ .

Part c)

$\displaystyle{\frac{z}{\var{h}}}-\var{j}=\var{k}$

$\displaystyle{\frac{z}{\var{h}}}=\var{k+j}$

$z=\var{ans3}$

Part d)

$\displaystyle{\frac{a-\var{l}}{\var{m}}}=\var{n}$

$a-\var{l}=\var{n*m}$

$a=\var{ans4}$

Part e)

$\var{p}$ $=$ $\var{q}(\var{r}+b)$

$\displaystyle{\simplify{{p}/{q}}}$ $=$ $\var{r}+b$

$\displaystyle{\simplify{{p-r*q}/{q}}}$ $=$ $b$

Part f)

$\displaystyle{\frac{\var{s}w}{\var{t}}}$ $=$ $\var{u}$

$\var{s}w$ $=$ $\var{u*t}$

$w$ $=$ $\displaystyle{\simplify{{u*t}/{s}}}$
