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 ![-14](https://tex.z-dn.net/?f=-14)
Step-by-step explanation:
We are given the equation: x + 8 <= 6
Let collect the like terms:
![x + 8 \leq 6\\x\leq 6 -8\\x \leq -2](https://tex.z-dn.net/?f=x%20%2B%208%20%5Cleq%20%206%5C%5Cx%5Cleq%20%206%20-8%5C%5Cx%20%5Cleq%20%20-2)
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 that you’re looking for is b
Answer:
A) X + Y = 12
B) 10Y + x = 10x + Y -18
B) 9Y = 9x -18 multiplying A) by -9
A) -9Y = 9x - 72 adding A and B we get
0 = 18x -90
x = 5
The number is 75
Double-Check
7 + 5 = 12
75 -57 = 18
