Answer:
Log x = 3 is the same as Log into base 10 of 3
Recall from Law of Logarithm: if Log a = x , then a = 10^ x
therefore If Log x = 3 , then x = 10^3 = 1000
Step-by-step explanation:
Answer:
(x, y) = (3, 5/2)
Step-by-step explanation:

I'll solve by elimination here. If you invert the second equation and add it to the first, 2y and -2y would cancel out.

Now just add those from top to bottom.

Nothing else needs to be done for that part. Now, you can pick either equation and use the known value of x to solve for y.

(x, y) = (3, 5/2)
