Questions: Solve for a. a+b-4=P a=m

Transcript text: Solve for $a$. \[ \begin{array}{l} a+b-4=P \\ a=m \end{array} \]

Solution

Solution Steps

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: \[ \boxed{a = P - b + 4} \]
