2log7-2r=0 with the 7 being a subscript(small)

Starting equation is 2log7(−2r)=0

First we can divide both sides by 2

log7(−2r)=0

Now we have to write the right side (0) as a logarythm.
Since 70=1, we can write 0 as log71, so the equation becomes:

log7(−2r)=log71

We can skip log signs because both sides are logarythms and the base is the same:

−2r=1

Now if we divide the equation by (-2) we get the

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
