Answer:
x = 28
Step-by-step explanation:
7(8 - x) = -5x
56 - 7x = -5x                 Distribute 7 to the parenthesis
56 = 2x                         Add -7x to both sides
28 = x                           Divide 2 to both sides
 
        
                    
             
        
        
        
f(-10) = 4
f(-2) = 4
Since y is constant while x isnt we just dont need to put x
f(x) = 4
