Answer: log(x+3)y₁ = -------------- log(4) log(2 + x)y₂ = ---------------- log(2)Step-by-step explanation:1) Here you must use the
property named change of base of the logarithm.
That rule is:

2) Changing to base 10 that is:

3) Using it with the given equation, you get:

4) Now, to set your
system you can make the left side of the equation equal to y₁ and the right side equal to y₂
log(x+3)
y₁ = -------------
log(4)
log(2 + x)
y₂ = ---------------
log(2)
And that is your system which is the first choice of the list.
