Verified Answer :

Solve the equation for h means that we want to obtain only one h on the LHS (or RHS) but it has to be "alone"
We are starting with
\(A =\frac{1}{2}*b*h\)             /*2
We can multiply both sides by 2 to reduce 1/2
\(2A=bh\)     
Now we can divide both sides by b to takes b to the LHS, so
\(\frac{2A}{b}=h\) - its our result
