Question

Please solve this equation: 5=X-4

 

Answer 1

To "solve" the equation, we want to get 'x' by itself. We have x-4 on the right side of the equation. What is the opposite operation of -4? Well, it is +4. So we add 4 to both sides. This looks like

 

5   = x - 4

+4     +4  

9   = x + 0

 

So we find that 9 = x, or x=9.

 

I hope this helps!
