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
The value of n is 3, by the commutative property.
For n = 1, 2, 3, 4, 5, ... the sequence goes 4, 5, 6, 7, 8, ...
No. If your trying to find n, then you subtract four from each side. n = 10 That would be subtraction property of equality.
3n + 4 = 7(- 4 from both sides)3n = 3(divide both sides by 3)n = 1
