The fourth number is 10.
if your asking for the answer its 8
4x - 8 = 8(x + 2)
There can be no number with an odd sum of 8 because 8 is not odd!
N - 8
4N + 8
The fourth number is 10.
Suppose the number is x. The sum of the number and two is x+2 Four times the sum is 4(x+2) The number times 8 is 8x 24 less than the number times 8 is 8x-24 4(x+2) = 8x-24 4x+8=8x-24 so 4x = 32 and x = 8

The sum of four and the product of three and a number xxxx.
Sum -7 to +8 = -28 + 36 There are four lines so 8/4 = 2.
This is simple algebra. Let the unknown number be n. Then the sum of this number and 8 = n + 8.
the sum of 8 and 4 times a number is 36
five times the sum of a number and 8 is -15.
4x - 8 = 8(x + 2)
4*(2x + 8) = 32
