<span><span>|x| + 9 </span>+ <span>−9 </span></span>≤ <span>7 + <span>−9
</span></span><span>|x| </span>≤ <span>−<span>2
</span></span>
Now solve the absolute value
(You can't because the absolute value would end up less than 0 and it's not possible for that to happen)
No Solution
Answer:
The value of x is 
Step-by-step explanation:
we have
------> equation A
In this problem we have
Substitute the value of g(x) in the equation A and solve for x
Divide by
