See the entire solution process below:
Explanation:
First, subtract
Now, divide each side of the equation by
Explanation:
To solve this equation, collect terms in n on the left side and numeric values on the right side.
add n to both sides.
#n+n+2=-14cancel(-n)cancel(+n)#
#rArr2n+2=-14# subtract 2 from both sides.
#2ncancel(+2)cancel(-2)=-14-2#
#rArr2n=-16# divide both sides by 2
#(cancel(2) n)/cancel(2)=(-16)/2#
#rArrn=-8#
#color(blue)"As a check"# Substitute this value into the equation and if the left side equals the right side then it is the solution.
#"left side " =-8+2=-6#
#"right side " =-14-(-8)=-14+8=-6#
#rArrn=-8" is the solution"#
