Final answer:
To solve for a in the equation z = m + a, subtract m from both sides. The resulting equation is z - m = a.
Step-by-step explanation:
The student is asking for assistance with solving for the variable a in the equation z = m + a. To isolate a, we need to subtract m from both sides of the equation. The steps to solve the equation are as follows:
- Subtract m from both sides: z - m = a.
- Now, a is isolated on one side, so the equation z - m = a is the solution.
So, if you are given specific values for z and m, you can substitute those in and calculate the value of a.
