Let x = hats she knitted 
Less than means to subtract and it’s an order switcher so it would be 
2x - 6 = 78 
First step: Add six to both sides -6 + 6 = 0 6 + 78 = 84
2x - 6 = 78
 + 6. +6
2x = 84
Second step: Divide the coefficient on both sides, two is the coefficient 
2x/2 = x 
2/84 = 42 
Therefore, the answer is x= 42
