For the equation to work, you have to have the same number on both sides of the equal sign
so to find ?, you can do:
13 - 2 = 12 - ? Simplify
11 = 12 - ? Subtract 12 on both sides
-1 = - ? Multiply -1 on both sides
1 = ?
The place value 8 in 281,480,100 is the 10th. And it is the same way in the other problem. How you get your answer is by counting like this EX: 1, 10, 100, 1,000, 10,000, 100,000... And so on.
<span>3x+4=y+5, then y+5=3x+4
It is called: reflexive property

<span>x = y and y = 10, then x = 10
It is called: equality substitution property

Answer:
the answer is x = 0
Step-by-step explanation:
Cancel equal terms on both sides of the equation:

Divide both side of the equation by 5.

Therefore, the answer is x = 0
