To solve this problem we must know that when any two lines intersect , a pair of opposite angles from the figure Will be equal
so that means that 

we can subtract twenty from each side


now we can subtract like terms

so we can get the final answer as
 
 
        
        
        
Answer:
 (3,-3)
Step-by-step explanation:
If a coordinate (x, y) is dilated by a factor k, the resulting coordinate will be (kx, ky)
Given the coordinate (1, -1), if dilated by a factor of 3, the resulting coordinate will be (3(1), 3(-1)) = (3, -3)
Hence the required coordinate will be (3,-3)
