# In Exercises 5 to 14, find the value of x in each proportion. a) x + 1 2 = 7 x − 1 b) x + 1 3 = 5 x − 2

To determine

a) To find:

The value of x in the given proportion.

Explanation

According to Means-Extremes Property, in a proportion, the product of the means equals the product of the extremes.

Calculation:

Consider, x+12=7xâˆ’1

Apply means-extremes property of proportion in x+12=7xâˆ’1.
