To get x alone, you have to divide -4.9 to both sides. The reason you have to divide is because division is the opposite of multiplication
This is what you call a one step equation
-4.9x = 9.8
x = 9.8/-4.9
x= -2
        
                    
             
        
        
        
N4=c
n times 4, n being a number of notebooks, would equal c, or the overall cost.
