Fast on both will give brainliest and lots of points

Problem 2)

Divide both sides by 200

⇒

then the following log rule is used on the left side:  

since we get:

To isolate x, we then multiply both sides by 10 and afterwards divide both sides by 3.

⇒ ⇒ ⇒

Problem 3)

⇒

then the following log rule is used on both sides:

the following log rule is used on both sides:

since we get:

To isolate x we subtract from both sides:

then we can use the following log rule on the right side:

then subtract 4x from both sides:

⇒

Divide both sides by -2

⇒

step-by-step explanation:

it's the only multiple of both and the least
