Understand the inequality: Understand the inequality.We are given the inequality 7+x<16, which means we need to find the value of x that, when added to 7, gives a result that is less than 16.
Isolate the variable x: Isolate the variable x.To find the value of x, we need to isolate it on one side of the inequality. We can do this by subtracting 7 from both sides of the inequality.7+x−7<16−7
Simplify the inequality: Simplify both sides of the inequality.After subtracting 7 from both sides, we get:x<16−7x<9
Check for errors: Check for any mathematical errors.We subtracted 7 from both sides correctly and simplified the inequality to find that x must be less than 9.
