#x=48#

Given:#color(brown)(" "8=x/6)# ..........................Equation(1)

Multiply both sides by #color(blue)(6)#

#color(brown)(8color(blue)(xx6)=x/6color(blue)(xx6))#

#48=color(brown)(x) xx(color(blue)(6))/(color(brown)(6))#

but #6/6=1# giving

#48=x#

'~~~~~~~~~~~~~~~~~~~~~~~~~~
Check:

substitute #x=48# into equation(1)

#color(brown)(8=x/6)color(blue)(" " ->" "8=48/6#

But #RHS->48-:6= 8#

So LHS=RHS = 8

LHS#-># left hand side
RHS#-># right hand side
