I think the rang numbers are -2 , 2 , -4 , and 2. i hope that correct.
If f(x) = 0 then
solutions
x = 7 , x = -4
hope it helps
X=alice
b=barry
c=charlene
x=15 more than b
x=15+b
c=2 times of b
c=2b
all together
x+c+b
15+b+2b+b
15+4b
they have 15+4b or 15+4 times of barry
if we want in terms of x
x=15+b
x-15=b
15+4(b)
15+4(x-15)
15+4x-60
4x-45
they have 4x-45 together
The first step would be to subtract 5 from both sides. We have to leave x alone so subtract five from both sides which will leave us with x=22
For the next one we would have to divide 3 by -4 to get w=1.3 Infinite so the 3 would have a small dash on top.
