Question

Consider this equation: 2x + 2 = 11 - x

Now consider the equation written as: 3x + 2 = 11
Which of the following is the correct property of equality that justifies rewriting the equation?
addition
subtraction
division

Answer 1

addition bc. you need adding to both sides x and will get this result of 3x+2 = 11

hope helped

Answer 2

Answer: "Subtraction" is the correct answer.

Explanation:

Since we have given that

`2x+2=11-x`

Now, consider the equation written as:

`3x+2=11`

Now, We will use the property of equality that justifies rewriting the equation :

`3x+2=11\\\\\text{ Subtracting 2 from both sides}\\\\3x+2-2=11-2\\\\3x=9\\\\x=(9)/(3)\\\\x=3`

Hence "Subtraction" is the correct answer.
