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

$\var{a}y + \var{d} = \var{b} +\var{c}y$

$y=\;$ Unnamed gap

Advice

Use the following steps in both parts to solve for unknown:

Part a)

1. Bring the terms of given variable to one side by changing signs.

Ex- $\var{a}y - \var{c}y$ = $\var{h}y$

2. Take all the constants to one side by changing signs

Ex- $\var{b}- \var{d}$ = $\var{w}$

3. Solving for y, we get-

$\ y$ = $\var{f}$

Part b)

1. Bring the terms of fractions of variables to one side by changing signs.

Ex- $\frac{\var{m}}{{y}} - \frac{\var{s}}{{y}} = \frac{\var{o}}{{y}}$

2. Take all the constants to one side by changing signs

Ex- $\var{t}- \var{n}$ = $\var{u}$

3. Solving for y, we get-

$\ y$ = $\var{g}$
