Answer:
<em>w = 15</em>
Step-by-step explanation:
We reverse the equation, so 11 + 4.
w=2 I need to write more the. 20 characters so I could send this but w=2 is the answer
3.5y
you answer is going to be 17
for domain x+4≠0
x≠-4
domain={R-{-4}}
R=all real numbers.
y(x+4)=x
yx+4y=x
yx-x=-4y
x(y-1)=-4y
so Range ={R-{-1}}
