Explanation:
#"subtract x from both sides of the equation"#
#2x-x-24=cancel(x)cancel(-x)#
#rArrx-24=0#
#"add 24 to both sides"#
#xcancel(-24)cancel(+24)=0+24#
#rArrx=24#
#color(blue)"As a check"# Substitute this value into the equation and if both sides are equal then it is the solution.
#"left "=(2xx24)-24=48-24=24#
#"right "=24#
#rArrx=24" is the solution"#
