Solve the equation for the variable b.
A = 1/2 h (b+B)
2/1*A = 2/1*1/2 h(b+B)
2A = h(b+B)
2A = bh+Bh
2A-Bh = bh <-----This is where I am stuck.
The only solution i can come up with, is that it is a muliplication for both variables on both sides, which needs to be inversed in order to get b by itself...
2A-Bh / h = bh / h
cross out the h i get:
2A-B = b
The real answer should be:
2A-Bh/h = b
A = 1/2 h (b+B)
2/1*A = 2/1*1/2 h(b+B)
2A = h(b+B)
2A = bh+Bh
2A-Bh = bh <-----This is where I am stuck.
