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+1x=2x3

Apply means-extremes property of proportion in x+1x=2x3.

2x(x)=3(x+1)2x2=3x+32x23x3=0x=(3)±

To determine
