5 answers

Is your equation?

x + 7 + 5 = 9

Are you supposed to solve for x?
its a V x + 7 + 5=9
the V is the real root number its 2nd and x2 on the graphing calculator
I answered this yesterday.
Replacve 7 + 5 with 12 on the left side.
Then subtract 12 from both sides of the equation.

I am assuming your variable is "Vx". You can only solve for one unknown when you have one equation.
sqrt(x) + 7 + 5 = 9 ??? maybe?

sqrt(x) = -3
x = 9 ?
or did you leave some parentheses out?
Now that you have explained what your "V" means, sqrt x = -3 and x = 9
