From the graph:

The Boston public library has 14.6 millions of volumes.

The Harvard University has 14.7 millions of volumes.

Let n represent the number of more volumes the Harvard University had than

the Boston public library.

Write the verbal expression to represent the situation: \ \

Rewrite the equation:

14.6 + n = 14.7

Subtraction property of equality:  if a = b, then a c = b c.

14.6 + n 14.6 = 14.7 14.6         (Subtract 14.6 from each side)

n = 14.7 14.6                                 (Additive inverse property:14.7 14.7 = 0) \ \

  n = 0.1                                                (Subtract: 14.7 14.6 = 0.1)

The Harvard University has 0.1 more millions of volumes than Boston Public

library.
