Answer:
"Let's represent the unknown number with the variable x.
We can represent " 6 added to twice a number and this sum is multiplied by 3" with the following expression:
3(2x + 6)
Also, we can represent "the number multiplied by 4 and 8 added to the product" as: 4x + 8
Since these two expressions are equal to one another, we can write: 3(2x + 6) = 4x + 8
Now solve for x using the distributive property and inverse operations:
3(2x + 6) = 4x + 8
6x + 18 = 4x + 8
6x + 18 - 4x = 4x + 8 - 4x
2x + 18 = 8
2x + 18 - 18 = 8 - 18
2x = -10
2x/2 = -10/2
x = -5
The unknown number is -5
