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"
