Find values of a and b that make the following equality into identity:

1.

2.

Step-by-step explanation:

1. Given:

To find a and b, add two fractions in right side:

So,

Two fractions with same denominators are equal when they have equal numerators, so

Equate coefficients:

From the second equation:

Substitute it into the first equation:

Hence,

2. Given:

Note that

To find a and b, add two fractions in right side:

So,

Two fractions with same denominators are equal when they have equal numerators, so

Equate coefficients:

From the first equation:

Substitute it into the second equation:

Hence,

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
