23 = 7x
23 = 7 X x (multiplication is the default operation in algebra)
You would then use the opposite function of multiplication, which is division
23 ÷ 7 = 3.28 (rounded)
therefore x = 3.28
Let's start from the left side, and manipulate it to get the right side, which would prove the identity.
We know that:
i)

ii)

.
From the above fundamental identities, we can rewrite the left hand side as:


,
which is what we needed to show.
