#x=6/5#

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"#
