Math Problem Statement
Solution
The inequality given is:
Step-by-step solution:
-
Start by isolating the term with the fraction: Add 2 to both sides to eliminate the constant term on the left:
-
Multiply both sides by 5 to eliminate the denominator:
-
Isolate : Add 22 to both sides:
-
Multiply through by to get rid of the negative sign. Remember to reverse the inequality when multiplying by a negative number:
