8+2n
2n+12=x
(92 x 2) - (9 x 2) = 162 - 18 = 144 The number is therefore 9.
16.5
the equation is 2x + 4 = x - 3 solving it yields x = -7
3*(n - 5) = 2*n + 11
Five more than twice a number is -13 find the number
There is no selected number so it would be a variable. The answer is 2n-9 (n is the number which you choose)
7
Let's call "a number" x. Then 5 more than twice x is 5 + 2x.
74658
2n + 2 = 2(n + 1)Since you have been given that it is twice a variable with the variable only, you have 2n, and adding 2 yields 2n + 2, or 2(n + 1).
Then the number is 3
8 more than twice a number d
5
One number is eight more than twice another if their difference is 25. The larger number is 42
n = number.2n + 6=====
