X = 81
sqrt(X) + 3 = 12 ( subtract 3 from each side )
sqrt(X) = 9 (square both sides )
X = 81 ( the square root of 81 is 9 )

I'll do ya one better - 12 plus 8 equals what?
x=5.54x+1= 2x+12-1 -14x=2x+11-2x -2x2x=11/2 /2x=5.5
Solving these simultaneous equations by the elimination method:- x = 1/8 and y = 23/12
-5x + 13 = -12 -5x = -12 - 13 = -25 x = -25/-5 = 5
if this is x squared -6x+6=0 then -6=b, a=1, c=6 6+ square root of -6 squared-4(6x1) - 6+ square root of (36-24) - 6+ square root of 12 - 6+ square root of 4 x square root of 3 - 6 + (2x square root of 3) - that is all divided by 2 multiplied by a meaning it is divided by 2. so x= 6 + or - (2 square root 3) divided by 2 srry steps are jmbled -
