After making 'a' the subject of the formula (M = ac - bd) the value of a is [tex]\rm a = \dfrac{M+ bd}{c}[/tex] and this can be determined by using the arithmetic operations.
Given :
Expression -- M = ac - bd
The following steps can be used in order to make 'a' the subject of the formula (M = ac - bd) :
Step 1 - Use arithmetic operations in order to make 'a' as the subject of the formula (M = ac - bd).
Step 2 - Write the given expression.
M = ac - bd
Step 3 - Add 'bd' on both sides in the above expression.
M + bd = ac - bd + bd
M + bd = ac
Step 4 - Now, divide by 'c' on both sides in the above expression.
[tex]\rm a = \dfrac{M+ bd}{c}[/tex]
