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"#
