Answer:
The amount that Obi initially had was £20
Step-by-step explanation:
Let
x ----> amount that Obi initially has
y ----> amount that Rudy has
we know that

----> equation A


----> equation B
Solve the system by substitution
substitute equation A in equation B

solve for y

Find the value of x

therefore
The amount that Obi initially had was £20

Answer:
u=-1
Step-by-step explanation:
-3|2-4u|+5<-13
-6+12u+5<-13
12u<-13-5+6
12u<-12
12u/12<-12/12
u=-1
For a fraction, if the denominator turns to 0, the fraction becomes undefined, and therefore, that's a restriction on a rational.
now, what values of "x" makes the denominator 0? let's check,
x+2 = 0
x = -2
so, if "x" ever becomes -2, then you'd get

so, the domain, or values "x" can take on safely, are any real numbers EXCEPT -2.
