Step-by-step explanation:
Given
Two integers a and b
The first statement in the question says, their sum is at least 30
The keyword "at least" means their sum can not fall below 30 and this is represented mathematically as
The next statement says their difference is at least 10 and b is greater;
The keyword "at least" means the same as used above (i.e. can not exceed); The second statement is represented as:
Hence, the system of inequality that represents the statements are:
Step One
Put the right side over a common denominator.
Step Two
Remove the brackets on the numerator in the last equality.
Step three.
This will seem kind of odd but take out the common factor (x) in the first two terms of the numerator.
Step Four
What you do next comes up very frequently in your second or third calculus course.
You have to notice that there are no xs in the numerators on the left side of the original expression
Therefore you have to make a - b = 0 so that the xs disappear on the right.
a - b =0
a = b
Step Five
Find a
a is all by itself on the numerator of the final result.
The original question has a 1 in the numerator. Therefore a = 1
Step Six
Solve for b
a = b
1 = b Answer
