#### Explanation:

#"collect x-terms on one side of the equation and numeric"#

#"values on the other"#

#"add 8 to both sides"#

#7+8+3x=6xcancel(-8)cancel(+8)#

#rArr15+3x=6x#

#"subtract 3x from both sides"#

#15cancel(+3x)cancel(-3x)=6x-3x#

#rArr15=3x#

#"divide both sides by 3"#

#15/3=(cancel(3) x)/cancel(3)#

#rArrx=5#

#color(blue)"As a check"# Substitute this value into the equation and if both sides are equal then it is the solution.

#"left side "=7+(3xx5)=7+15=22#

#"right side "=(6xx5)-8=30-8=22#

#rArrx=5" is the solution"#
