To solve for a in terms of other variables, we need to isolate a on one side of the equation. We have two equations: a+b−4=P and a=m. Since a=m is already solved for a, we can substitute m into the first equation to express a in terms of b and P.
Step 1: Isolate a
We start with the equation:
a+b−4=P
To isolate a, we rearrange the equation:
a=P−b+4
Step 2: Substitute a
We also have the equation:
a=m
By substituting m into the rearranged equation, we can express a in terms of b and P:
m=P−b+4
Final Answer
Thus, the expression for a in terms of b and P is:
a=P−b+4
