Answer: x=6
Step-by-step explanation:
To solve for x, we want to isolate the variable.
[get common denominator]
[add fractions]
[combine like terms]
[multiply both sides by 8]
[subtract both sides by 14]
[divide both sides by 15]

Now, we know that x=6.
Function: y = 4|x| - 1.
Domain: R (all real numbers).
Range: As we know, the absolute value of x is always a non-negative number:
|x| >= 0
4|x| >= 4 * 0
4|x| >= 0
4|x| - 1 >= -1
y >= -1 <----- this is the range
I hope this helps. =)
