Answer: where’s the diagram
Step-by-step explanation:
 
        
                    
             
        
        
        
Make each equation equal to each other, then solve for x. 
-x+2=4x+7
-x-4x=7-2
-5x=5
X=-1
Sub x into one if the y formulas to find y
Y=4x+7
Y=4(-1)+7
Y=-4+7
Y=3
See my picture for how to graph the points. 
Hope this helps!
