Let x=aunt's agethen x-14=Mrs West's ageso we have:60-(x-14)=x-40 simplify60-x+14=x-40 subtract x from each side and also subtract 60 and 14 from each side60-60-x-x+14-14=x-x-40-60-14 collect like terms 
-2x=-114x=57------------aunt's agex-14=57-14= 43----------Mrs West's ageck60-43=57-4017=17 
        
             
        
        
        
Rearrange: 2y = 6 -3x
2y = - 3x + 6 
y = -1.5x + 3 
Now, substitute, perpendicular lines have the same gradient so: 
-1 = -1.5 (2) + c
- 1 = -3 + c 
2 = c 
 equation for new line: y = 1.5x + 2
        
             
        
        
        
0.125 sorry if I’m wrong :(
