Answer:
or
Step-by-step explanation:
you have a definition for the variable m:
and then you are asked to find the equivalent equation to:
in terms of m, what we need to do is substitute all the we find in the expression, for an m (because of the definition ), this way we get the following:
we still have to write in terms of m for that we factor a -7, and we get:
we have found an equivalent to which contains and since we know that :
and we substitute this into the equation
this equation is now what we anted, the original expression in terms of m. you can represent the result like this:
or what is the same:
