n + 7 = 10subtract 7 from both sidesn = 3
n= -2
2+n-3 = 6 n = 6+3-2 n= 7
3n+3=n+7 3n+3-n=n+7-n (subtract n from both sides) 2n+3=7 2n+3-3=7-3 (subtract 3 from both sides ) 2n=4 2n/2=4/2 (divided by 2 on both the sides) n=2 Answer: n=2
3n+1=7 3*2+1=7
n + 7 = 10subtract 7 from both sidesn = 3

n = 8
2+n-3 = 6 n = 6+3-2 n= 7
2n plus 7 equals 19 2n equals 12 n equals 6
7 + n = 14 n = 7
3n+3=n+7 3n+3-n=n+7-n (subtract n from both sides) 2n+3=7 2n+3-3=7-3 (subtract 3 from both sides ) 2n=4 2n/2=4/2 (divided by 2 on both the sides) n=2 Answer: n=2
3n+1=7 3*2+1=7
n = 7. 3(7) + 7 = 28. 21+7=28
n=6
If n + 7 = 12, then n = 12 - 7
