Answer:

x = 1 + 0.5 * 10^7

Step-by-step explanation:

Use log(a) + log(b) = log(ab).

log(x-1) + log(2) = 7 <=> log(2(x-1)) = 7 <=> log(2x-2) = 7

Using log(a) = b <=> a = 10^b

log(2x-2) = 7 <=> 2x-2 = 10^7 <=> 2x = 2 + 10^7 <=> x = 1 + 0.5 * 10^7

-5x=25 how to solve this problem

Sidana [21]

X = -5

The goal of this problem is to solve for x.

To solve x in this problem you need to find a way to get it by itself on the left side, the way to do this is divide -5x by -5.

You then also have to do the same for the right side. This gives you -5.
