Exercise 73 Page 300

We can solve for the variable by using the Cross Products Property.

n=- 10

Practice makes perfect

To solve the proportion, we will use the Cross Products Property.

7/n=- 35/50

Cross multiply

7* 50=- 35* n

Multiply

350=- 35n

.LHS /(- 35).=.RHS /(- 35).

- 10=n

Rearrange equation

n=- 10

Therefore, the solution to the given equation is n=-10.
