Answer 1

$\huge\underline\mathfrak\pink{♡Answer♡}$

➡️The Addition Properties of Equality are keys to manipulating equations.

➡️They state that when adding the same number from both sides of the equation, the equation still holds!

✴When is this technique useful? ✴

➡️For example,

➡️ If we have the following equation:

➡️x+4=10

➡️We want to have only x on the left, that way we find out what it is.

➡️We know if we subtract 4 on both sides of the equation, the equation still holds.

➡️x+4−4

➡️10−4x

➡️6

✴Practice✴

x+5−2=10

How can we find out what x is?

Subtract 5 and add 2 on both sides.
