Answer:
the zero property
Step-by-step explanation:
meaning any number multiplied by zero gives zero
Answer:
C
Step-by-step explanation:
Given
+ 
← factor the denominator of first fraction
= 
+
Multiply the numerator/ denominator of second fraction by (x + 2)
= + 
The denominators are now common, so add the numerators leaving the denominator, that is
= 
= 
→ with numerator 4x + 6 → C
Answer:
infinitely many
Step-by-step explanation:
Add 12-y to both sides of the second equation to put it into standard form like the first equation:
y +(12 -y) = (x -12) +(12 -y)
12 = x - y . . . simplify
x - y = 12 . . . . second equation in standard form
We see this is identical to the first equation. That means every solution of the first equation is also a solution of the second equation. There are infinitely many solutions.
