7n+10
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
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

(n2 + n)/2 1+2+3+4+5+n= 15+n
The expression "n plus 3" can be represented as ( n + 3 ). To find the first five terms, we can substitute the values ( n = 1, 2, 3, 4, ) and ( 5 ) into the expression. The first five terms are: ( 1 + 3 = 4 ) ( 2 + 3 = 5 ) ( 3 + 3 = 6 ) ( 4 + 3 = 7 ) ( 5 + 3 = 8 ) Thus, the first five terms are 4, 5, 6, 7, and 8.
If n = 7, then 5n + 4 = 5 x 7 + 4 = 39.
3n + 9 = 3(n + 3)
n² - 10n + 24 = 0 You need two numbers that multiply to equal 24. They have to add to equal -10. -6 times -4 is 24 -6 plus -4 is -10 Your answer is (n - 6)(n - 4).
Yes. Multiplying out the brackets on the second one: 4(n + 3) = 4×n + 4×3 = 4n + 12.
3 + 7 is an ADDITION sum
