Answer:
Reflexive property
Step-by-step explanation:
The statement says that some number is equal to itself.
That's the reflexive property.
By plunging 5 into the equation as x, you have the equation
7(5) - 15
7 * 5 = 35 so
35 - 15
f(5) = 20
Look at deonomators
assuming that the deonomenators are 5x+15y and 2x+6y
find their LCM
factor
5x+15y=5(x+3y)
2x+6y=2(x+3y)
LCM=10(x+3y)=10x+30y
multiply 2/(5x+15y) by 2/2=4/(10x+30y)
multiply 1/(2x+6y) by 5/5=5/(10x+30y)
if we add them
9/(10x+30y)
