Answer: To solve for A in the equation -BA + g² = MA, we can start by isolating the A variable on one side of the equation.
We can start by adding BA to both sides of the equation:
-BA + BA + g² = MA + BA
Simplifying the left side by cancelling the -BA and +BA terms:
g² = MA + BA
Next, we can factor out the A variable from the right side:
g² = A(M + B)
Finally, we can divide both sides by (M + B) to isolate the A variable:
g² / (M + B) = A
So the solution for A is:
A = g² / (M + B)
