Explanation:
#"isolate 5x by subtracting 2 from each side of the equation"#
#5xcancel(+2)cancel(-2)=8-2#
#rArr5x=6#
#"to solve for x divide both sides by 5"#
#(cancel(5) x)/cancel(5)=6/5#
#rArrx=6/5#
#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.
#(cancel(5)xx6/cancel(5))+2=6+2=8#
#rArrx=6/5" is the solution"#
