Answer:
Step-by-step explanation:
Evaluating the numerator and denominator before evaluating
Using the rule of exponents
⇔ 
, 
= 1
Thus
y² ← substitute values into expression
= 
× 4² = 
× 16 = 
and denominator
= 1 × 4³ = 1 × 64 = 64
Now dividing
÷ 64
= × 
( cancel 16 and 64 )
= 
=
Answer:
One number is 15 and 3 less than that is 12 so that is your other number
Remember the order of operations.
Dividing fractions means multiplying a reciprocal.
3÷1/3=3×3/1=9
9-9+1=1
1 is your answer.
:)
1) find x
y=1/(x+3) -4
y+4=1/(x+3) -4+4
y+4=1/(x+3)
x+3 =1/(y+4)
x= 1/(y+4) - 3
2) change x on y , and y on x
x= 1/(y+4) - 3
y= 1/(x+4) - 3 This is an answer.
