kiakat · Answer

You're first step is to isolate the variable. How would you do that?

i dont know .. can u show me how to do it @KiaKat

kiakat · Answer

Isolating the variable means you have to get the x term on one side. What do you have move in order to do that??

anonymous · Answer

i dont understand sorry

kiakat · Answer

okay well you need to get x^2 on one side of the equation. So to do that you'd have to subtract the +2 from both sides of the equation.

  2+x^2=18
-2            -2

so then you'd have x^2=16
