Answer:

#n=6#

Explanation:

first, combine like terms

#color(red)(15n)+16+color(red)(4n)=130#

#color(red)(19n)+16=130#

then, subtract 16 from each side

#19n+16color(red)(-16)=130color(red)(-16)#

#19n=114#

finally, divide both sides by 19

#(19n)/color(red)(19)=114/color(red)19#

#(cancel(19)n)/cancel(19)=114/19#

#n=114/19#

#n=6#

Answer:

#n = 6#

Explanation:

#15n + 16 + 4n = 130#

Start by simplifying the equation

#19n + 16 = 130#

Subtract #16# from both sides

#19n + 16 - 16 = 130 - 16#

#19n = 114#

Divide both sides by #19#

#(19n)/19 = 114/19#

#n = 6" "# (Ans)
