Final answer:
The expression relating m1 to m2 in terms of m2 is m1 = m2.
Step-by-step explanation:
The question asks to write a new expression relating m1 to m2 in terms of m2, numerical coefficients, and given values. Let's assume that the given equation is:
m2 = m1 + m2
We can rewrite this equation to isolate m1 by subtracting m2 from both sides:
m2 - m2 = m1 + m2 - m2
Simplifying the equation:
m1 = m2
The new expression relating m1 to m2 is simply m1 = m2.
