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.

Yvette is starting a jewelry business. She spends $120 on supplies and makes 18 necklaces. She wants to earn a profit equal to 3
kiruha [24]

Yvette wants to earn a profit of $360, then. That means she has to make a total of $480. 480 divided by 18 is 26 and 2/3. That basically rounds up to $26.67.


480 = 18x


360 = 18x - 120


120(3) = 18x - 120


(I'm not that good at this, so don't take my word for it)
