you want to get N's on one side alone and the numbers on the other side alone, so move 5n to the left and tell me what you have left

-5 always do the oppisite of what you have on the other side so the 5n is positive you need to subtract 5n from both sides and what would your formula look like?

still don't understand

Add -5n to both sides -5n+9n-7=5n+5-5n
anonymous
  • anonymous
9n-7=5n+5 first subtract 5n from both sides which equal 4n-7=5 then subtract -7 from both sides but since it is a negative it equals a positive so add -7 from both sides which equal 4n=-2 then divide 4 with -2 which equals n=-2
