Explanation:
"multiply all terms on both sides of the equation by 4 "
"to eliminate the fraction"
cancel(4)xx(6n)/cancel(4)+(4xx2)=(4xx-16)
rArr6n+8=-64
"subtract 8 from both sides"
6ncancel(+8)cancel(-8)=-64-8
rArr6n=-72
"divide both sides by 6"
(cancel(6) n)/cancel(6)=(-72)/6
rArrn=-12
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.
"left "=(-72)/4+2=-18+2=-16=" right side"
rArrn=-12" is the solution"
