You need to give me the options
Well... all u have to do is 85 divided by 4 which equals 21.25..... unless there is another part of the question!!
1: multiple both sides by 2
Ex:-7n+10=-32
2: subtract 10 from both sides
Ex: -7n=-42
3:divide both sides by -7 to get n alone
Ex: n=6
Answer is 6 and the process is elimination!
