A = 1/2 bh
To solve for h, need to made h at one side
A = 1/2 bh
so, 2A = bh
divide both sides by { b }
so, 2A/b = bh/b
so, h = 2A/b
=====================================================
f = 9/5 c + 32
to solve for c : make c alone on the right side
so, we need to remove 32 and 9/5
at first we remove 32 it is positive, goes to another side (-32)
so,
f - 32 = 9/5 c
Now, c is multiplied by 9/5
so, goes to another side as 5/9
because the operation / will be flipped
But note to make () over
so, 5/9 ( f - 32 ) = c
