Answer:
Subtraction.
Step-by-step explanation:
We have been given an expression: 
.
Simplify our given expression:
Subtract 4 from both sides of equation:
Divide both sides of equation by 10:
Therefore, the missing reason for the shown argument is subtraction.
We would plug in x to all of those equations. So, 3(4+4)(4+1)/(4+2)(4-2). This would be 3(8)(5)/(6)(2). Then multiply them. 3(8)(5) would be 120. (6)(2) would be 12. Then divide 120 and 12 to get 10.
