To find 8 times the sum of a number and 5, you first need to calculate the sum of the number and 5. Let's say the number is represented by 'x'. So, the sum of the number and 5 would be x + 5. Then, you would multiply this sum by 8 to get the final result, which would be 8(x + 5) or 8x + 40.

First, write an equation: 8(n+5)
Next, distribute: 8n+40
Thats it. (Normally, there would be an = sign to solve for n. For example, you would have 8n+40= 64, then 8n would equal 24, and n would be 3.)
(3a-8) + 5x(a)
5
s= -8 + n, or s=n - 8, where s is the sum and n is the number
The sum of fifteen times a number and eight.
