1) Lesson Objectives:
You should be able to
Make a variable the subject of the equation.
express a variable in terms of other variables.
Always look through all examples in textbook before lesson.
Possible ways that they may ask this type of questions.
Eg: 2a + b =3c
a) Make a the subject of the equation.
b) Express a in term of b and c.
Both (a) and (b) are asking for the same thing. It is just asked in a different way.
Answer:
2a + b = 3c
2a = 3c - b
a = (3c-b) / 2
