Question

3sqrtx-4=9 what is x? please help

Answer 1

what do you think you'd do next? bearing in mind you'd want to isolate "x"

Answer 2

uhm..you subtract 4 from 9? o.0 i really dont know

Answer 3

yes :)

Answer 4

so you'd be left with \(3\sqrt{x}=5\)

Answer 5

then divide both by 3, then to get rid of the \(\sqrt{}\), raise both to 2 power

Answer 11

\(3\sqrt{x}-4(+4)=9(+4)\) and then the rest, divide by 3 and raise by 2power
