**Solve the inequality. Graph and check your solution.**

** **

$x+4<3$

The solution for the inequality is $x<-1$.

In this type of inequality, Simply use the **property of addition or subtraction of suitable number on both Left Hand Side & Right Hand Side **to maintain the inequality and also the variable & numbers should be at the different sides in the equation.

Since, the equality is $x+4<3$.

Here, to simplify this inequality, subtract $-4$ to both side on the above

$\begin{array}{l}x+4<3\\ x+4-4<3-4\\ x<-1\end{array}$

Since, in the expression $x<-1$

So, this expression means that the value of *x* should be smaller than $-1$.

So, Put $-2,-3,-4,-5.......so\u200aon$ in $x+4<3$ to check whether the inequality hold or not

Put $x=-2$ in inequality,

$\begin{array}{l}x+4<3\\ -2+4<3\\ 2<3\end{array}$

It holds the equation

Again, put $x=-3$ in equality

$\begin{array}{l}x+4<3\\ -3+4<3\\ 1<3\end{array}$

It also holds the inequality.

So, the expression $x<-1$ correctly holds the inequality.

**Graphical Interpretation**

Following is the graph of the expression $x<-1$ to get the proper graphical representation to know the points.
