Answer:

x=e^2/5

Step-by-step explanation:

log(20 x) - log(4) = 2

Add log(4) to both sides:

log(20 x) = 2 + log(4)

Cancel logarithms by taking exp of both sides:

20 x = 4 e^2

Divide both sides by 20:

And we get Answer:

x = e^2/5

Pls answer asap 7 - 3 r = r - 4 ( 2 + r)​
Marianna [84]

Answer:

no real answer

Step-by-step explanation:

distribute the -4 and combine all of the like terms on the left side = r-8-4r, then -8-3r

then we have 7-3r=-8-3r

from here, we can already tell that there's no real answer. this is because the two -3r will cancel, leaving no variable.

since 7 doesn't equal -8, there is no answer.

if, for example, the value on both sides of the equal sign were the same after the variable was eliminated, then your answer would be all real numbers
