When solving an equation, why is it necessary to perform the same operation on both sides of an equal sign?
Anna007 [38]
In order to keep the equation right, both sides have to balance each other. When you only perform an operation ( I'm assuming you're talking about division or multiplication) on one side, it messes up the balance because now one side is larger than the other.

Please help me it’s due tomorrow
Ierofanga [76]

Answer:

8 units

Step-by-step explanation:

so there is something called Pythagorean thereon and it states that a^2+b^2=c^2

and 6 is either a or b

and c is ten so

6^2+b^2=10^2

36+b^2=100

b^2=64

here you need to find the square root in order to delete the power so

\sqrt{b} =\sqrt{64\\\\

b=8

or

x=8
