Hey there!
[tex]13+15+18+\frac{x}{4} <21[/tex]
To get x, simplify both sides of the inequality.
[tex]\frac{1}{4}x+46<21[/tex]
Now we have to minus(subtract) 46 from both sides.
[tex]\frac{1}{4}x+46-46<21-46\\ =\frac{1}{4}x<-25[/tex]
In the last step, we'll have to multiply both sides by 4.
[tex]4*(\frac{1}{4}x)<(4)*(-25)=x<-100(ANSWER)[/tex]
For the graph.
Hope this helps!
