When you have several resistors in parallel, their equivalent resistance is the reciprocal of the sum of their individual reciprocals.
When there are only two of them, it gets a lot easier. In that case, their equivalent resistance is equal to
(their product) divided by (their sum).
Equivalent = (7 x 93) / (7 + 93)
Equivalent = (651) / (100)
Equivalent = 6.51 ohms .
