Question

A= (f+gDiv by 2)h solve for g

how can i solve for g?

Answer 1

Which one?\[
A = (f + \frac g2)h ~~~~\text{ OR }~~~~ A = \left(\frac{f+g}{2}\right)h
\]

Answer 2

second one

Answer 3

\[A = \left(\frac{f+g}{2}\right)h \\
\text{Multiply by 2:} \\
2A = (f+g)h \\
\text{Divide by h:} \\
\frac{2A}{h} = f + g \\
\text{Subtract f:} \\
\frac{2A}{h} - f = g \\
g = \frac{2A}{h} - f = \frac{2A-fh}{h}
\]

Answer 4

is that it? Or is there more?
