Please help me!!!<br>What is the value of n?<br>2n = 8 + 4n<br>A)-4<br>B) 4<br>C)-4/3<br>D)4/3
erica [24]
To get the value of n u have to set n by itself, first we have to set teh smallest n to teh other side this will give you 0=8+2n now subtract the 8 from both sides because it is positive and the only way to get rid of a positive is with a negative this will give you -8=2n, now to set n by itself divide by 2 in both sides because in order to get rid of a multiplication you have to divide, this will give you n=-4, so your answer will be letter A

Hope this helps
