Solution - Linear inequalities
Step by Step Solution
Rearrange:
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
x/4-(11)<0
Step by step solution :
Step 1 :
x
Simplify —
4
Equation at the end of step 1 :
x
— - 11 < 0
4
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 4 as the denominator :
11 11 • 4
11 = —— = ——————
1 4
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
x - (11 • 4) x - 44
———————————— = ——————
4 4
Equation at the end of step 2 :
x - 44
—————— < 0
4
Step 3 :
3.1 Multiply both sides by 4
Solve Basic Inequality :
3.2 Add 44 to both sides
x < 44

Life is not binary (no matter how badly Tiger wishes it was) and we are often faced with questions with more than one answer. This is why we need inequalities. How much of a product should be produced to maximize a company's profit? What is the number of tickets that you need to sell for your band's show to be profitable? How much money do you need to make during summer break to book a ski trip in the winter? By helping explain the relationships between what we know and what we want to know, linear inequalities can help us answer these questions, and many more!
