(40)/z = 2/1

\frac{40}{z} = \frac{2}{1}

z = 20

Solution steps

\frac{40}{z} = \frac{2}{1}

Cross multiply

40 = z \cdot 2

Switch sides

z \cdot 2 = 40

Divide both sides by

2

z = 20

Verify Solutions

Find undefined (singularity) points:

z = 0

Combine undefined points with solutions:

z = 20

d, B = \frac{L}{4 π d ^{2}}

2 = \frac{20}{x ^{2} + 2}

\frac{x ^{2} - 2 x}{x ^{3} + 3 x + 1} = 0

\frac{x}{10 x ^{2} + 10 x ^{2} + 1} = 0

(x + 7)^{- 1} = x^{- 1} + x
