Answer:

Subtraction.

Step-by-step explanation:

We have been given an expression: $7x+3x+4=24$ .

Simplify our given expression:

$(7+3)x+4=24$

$10x+4=24$

Subtract 4 from both sides of equation:

$10x+4-4=24-4$

$10x=20$

Divide both sides of equation by 10:

$\frac{10x}{10}=\frac{20}{10}$

$x=2$

Therefore, the missing reason for the shown argument is subtraction.
