#x= 1/2#

Explanation:

Having the variable in the denominator can be a problem, but in this case there are 2 ways to fix the problem because there is only one term on each side of the equal sign.

#1. "Invert the fraction"#

#8/color(red)(x) = 16/1 " "rarr " " color(red)(x)/8 = 1/16 " "larrx# is in the numerator

#x= 8/16 " "larr# multiply by 8

#x = 1/2#

#2. "Cross multiply"#

#8/x = 16/1#

#16x = 8xx1" "larr div 16#

#x = 8/16#

#x = 1/2#
