How do you work out 7n plus 1 equals 6n plus 8?
7n + 1 = 6n + 8 7n=6n+7 (minus 1 from each side) n=7 (7n-6n equals n, you are left with n=7)
-5n minus 4p plus 7n plus 2?
-2n - 4p + 2. Without knowing n and p, that's the best you get.
How do you solve 1 minus 7n equals 15 minus 5n?
1 - 7n = 15 - 5n Add 5n to each side: 1 - 7n + 5n = 15 -5n + 5n ie 1 - 2n = 15; subtract 1 from each side: -2n = 14 divide both sides by -2: n = -7

What is the nth term of this sequence -2 -9 -16 -23 -30?
There is a difference of '-7' between each term . Hence '-7n' The first term 'n' is '-2' Hence n = 1; -7(1) + c = -2 -7(1) + c = -2 c = -2 + 7 c = 5 Hence nth term is -7n + 5 Verification When n = 4 -7(4) + 5 = -28 + 5 = -23 ( As required).
