Solve for m in the equation below.

A=1/2(m+n)h

To solve for m, we can start by isolating the variable by multiplying both sides of the equation by 2:

2A = (m + n)h

Next, divide both sides of the equation by h:

(2A)/h = m + n

Finally, subtract n from both sides of the equation:

m = (2A/h) - n

So, m = (2A/h) - n is the solution.
