Question

Tell whether the value is a solution of the
- 5 = QS)-1; S = 10

Answer 1

Answer:

S=− $\frac{4}{Q}$

Step-by-step explanation:

−5=(QS)−1

Swap sides so that all variable terms are on the left hand side.

QS−1=−5

Add 1 to both sides.

QS=−5+1

Add −5 and 1 to get −4.

QS=−4

Divide both sides by Q.

$\frac{QS}{Q}$=$\frac{-4}{Q}$

Dividing by Q undoes the multiplication by Q.

S= $\frac{-4}{Q}$

Divide −4 by Q.

S=− $\frac{4}{Q}$
