Question

Solve the inequality. Graph the solution. a +18 < 7

Answer 1

Given the following inequality:

`a+18<7​`

To solve it, you need to solve for "a" by applying the Subtraction property of Inequalities and subtract 18 from both sides, as you can see below:

`\begin{gathered} a+18-(18)<7-(18) \\ a<-11 \end{gathered}`

To graph it on a number line we must put a dot or a circle where -11 is.

Since the symbol of the inequality is <, the dot or the circle must be unfilled and the line must go from -11 to the left (because it is the direction of the numbers that make the given inequality true).

Then, you get:
