Let n be the number. Then what you're asking for is 6n+(n+7).
(-8,1)
If: 2+3x = 77 Then: x = 25
The number is 36
The numbers are 7 and 28 which equals 35 when added together
You get the sum of 11 two ways; 5,6 and 6,5.
2*(n+15) = 6n
Let's call the number XTwice the number would be 2XFour times the same number would be 4XThe sum of these two is 2X + 4X = 6XThe answer is therefore six times the number.
Assuming the number is n; then: 2n + (6n + 5) = 8n + 5 That means five added to eight times the number

The sum of two number times a third numberis equal to the sum of each addend times the third number
