The resistors \(\displaystyle 70 \ \Omega\) and \(\displaystyle 30 \ \Omega\) are in parallel, so we can combine them as:
\(\displaystyle \left(\frac{1}{70} + \frac{1}{30}\right)^{-1} = 21 \ \Omega\)
\(\displaystyle \left(\frac{1}{70} + \frac{1}{30}\right)^{-1} = 21 \ \Omega\)

The resistors \(\displaystyle 20 \ \Omega\) and \(\displaystyle 5 \ \Omega\) are in parallel, so we can combine them as:
\(\displaystyle \left(\frac{1}{20} + \frac{1}{5}\right)^{-1} = 4 \ \Omega\)
\(\displaystyle \left(\frac{1}{20} + \frac{1}{5}\right)^{-1} = 4 \ \Omega\)
