Question

6 + 9= −3 −21 –6

I need help how do u solve steps plz

Answer 1

Add 6+9=15
So now your equation look like: 15=-3-21-6
Now solve the left side of the equation by subtracting: -3-21-6=-30
So now the equation looks like this: 15=-30
Since the equation is not equivalent, the equation is false.
Let me know if you have any questions!
