Explanation:
#"collect terms in x on the left side of the equation and"#
#"numeric values on the right side"#
#"subtract "5x" from both sides"#
#9x-5x-13=cancel(5x)cancel(-5x)+11#
#rArr4x-13=11#
#"add 13 to both sides"#
#4xcancel(-13)cancel(+13)=11+13#
#rArr4x=24#
#"divide both sides by 4"#
#(cancel(4) x)/cancel(4)=24/4#
#rArrx=6#
#color(blue)"As a check"# Substitute this value into the equation and if both sides are equal then it is the solution.
#"left "=(9xx6)-13=54-13=41#
#"right "=(5xx6)+11=30+11=41#
#rArrx=6" is the solution"#
