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

Answer 4

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

Answer 5

i dont understand sorry

Answer 6

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

Answer 7

oh okay thanks
