Isolate the square root, square both sides, then solve for x. Answer: #x=-4#

#1/16sqrt(12-x)=1/4#

First we want to isolate the square root by multiplying both sides by 16:

#16*1/16sqrt(12-x)=1/4*16#

#sqrt(12-x)=4#

Now we square both sides and solve for x:

#sqrt(12-x)^2=4^2#

#12-x=16#

#x=-4#

Therefore our answer is #x=-4#.
