#x=(S-6pic^2)/(5pic)#

Explanation:

#"express as"#

#5picx+6pic^2=S#

#"subtract "6pic^2" from both sides"#

#5picxcancel(+6pic^2)cancel(-6pic^2)=S-6pic^2#

#rArr5picx=S-6pic^2#

#"divide both sides by the multiplier of x "5pic#

#(cancel(5pic) x)/cancel(5pic)=(S-6pic^2)/(5pic)#

#rArrx=(S-6pic^2)/(5pic)#
