Gather like terms. The - 2 and 4; the 7n and 3n. 7n - 2 + 3n + 4 = 10n + 2
3n+2+3n+2=6n+4
well the first four terms are n=1,2,3 and 4 so just substitute those numbers into k=3n so k= 3,6,9,12
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
2+3n+2+9n would equal 4+12n after adding all like numbers.
Gather like terms. The - 2 and 4; the 7n and 3n. 7n - 2 + 3n + 4 = 10n + 2
They are 7, 10, 13, 16 and 19.
3n+2+3n+2=6n+4
3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (4) = 3n + 6
well the first four terms are n=1,2,3 and 4 so just substitute those numbers into k=3n so k= 3,6,9,12
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
They are 7, 10, 13, 16 and 19.
3n + 4 = 7(- 4 from both sides)3n = 3(divide both sides by 3)n = 1
-5(3n plus 4) 40 is a set of disjointed expressions: it is not a formula and so cannot be solved.
n=4
The answer to -2(4+3n)=24 is:-5.33
