Answer:

Step-by-step explanation:
Given

Required:
Simplify
We start by opening the bracket


Collect Like Terms

Hence, the equivalent expression is 
 
        
             
        
        
        
4x - 5y = 24
4(6) - 5(0) = 24
24 - 0 = 24
24 = 24 (correct)....so (6,0) is a solution
4(1) - 5(-4) = 24
4 + 20 = 24
24 = 24 (correct)...and (1,-4) is a solution
