ANSWER
B. 10
EXPLANATION
We need to find the value of x first.
It was given that the perimeter of triangle XYZ is 24.
This means that:
XY+YZ+XZ=24
we substitute the expression in terms of x to get;

This implies that


Divide both sides by 4 to get;

|WY|=|ZX|=13-3=10
 
        
                    
             
        
        
        
<span>2x-3y=18 
when x = 3
2(3) - 3y = 18
6 - 3y = 18
-3y = 12
   y = -4
so(3, -4) is the solution
