Explanation:
#"multiply through by 3"#
#cancel(3)xx(2n-1)/cancel(3)=3xx10#
#2n-1=30#
#"add 1 to both sides"#
#2n=30+1=31#
#"divide both sides by 2"#
#(cancel(2) n)/cancel(2)=31/2rArrn=31/2#
#color(blue)"As a check"# Substitute this value into the left side of the equation and if equal to the right side then it is the solution.
#(2xx31/2-1)/3=(31-1)/3=30/3=10#
#n=31/2" is the solution"#
