Final answer:
The solution to the inequality 2x < 20 is all real numbers less than 10, as determined by dividing both sides of the inequality by 2.
Step-by-step explanation:
The student's question involves solving the inequality 2x < 20. To find the solution to this inequality, we should divide both sides by 2, which will isolate the variable x on one side. This is a fundamental method of solving linear inequalities that is commonly taught in mathematics.
Divide both sides by 2:
This tells us that the solution to the inequality is all real numbers x that are less than 10. It's important to remember that this inequality does not include the number 10 itself, as the inequality is strictly less than, not 'less than or equal to.'
