Solve for b: R = 3a2b?
Is it R over 3a2 or 3a2 over R or 3a - R or R - 3a2

Since b is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation.
Divide each term in the equation by 3a^(2).
Simplify the left-hand side of the equation by canceling the common factors.

R = 3a²b
=> To make b the subject of formula in the equation above, simply requires you to divide both sides by 3a², i.e.
R/3a² = 3a²b/3a²
=> By cancelling 3a² from both the numerator and denominator at the right hand side of the equation above, you'll have
R/3a² = b
Hence b = R/3a² ...AnsSource(s): The websites listed below will be of a good help in letting you understand the change of subject of a formula - http://www.bbc.co.uk/schools/gcsebitesize/maths/al... http://www.mathsisfun.com/algebra/equation-formula... http://www.maths.com/algebra/change-the-subject-of... http://www.skoool.co.za/studynotes/maths/id230.htm
