Answer:
The possible values of x is given by
and they include: -2, -3, -4, -5, -6 and so on
The greatest possible value of 7x is 
Step-by-step explanation:
We are given the equation: x + 8 <= 6
Let collect the like terms:

Therefore, x <= -2 and the possible values include: -2, -3, -4, -5, -6 and so on
To find the greatest possible value of 7x is when x = -2.
.
The answer is 16 because you have to do the exponents, than the division, then the subtraction, and lastly, the addition.
