Step-by-step explanation:
I believe you meant your question to be 'log(2x + 1) = 3x - 2.' The simplest approach to this problem would be to assign 'y' to each side of the given equation, giving us the system of equations we need.
y₁ = log(2x + 1),
y₂ = 3x - 2
By dividing the given equation into these two equations, we can equate one another so that y₁ = y₂. Therefore their intersection will be (1) the value of y₁, (2) the value of y₂, and (3) the solution to the system of equations. Hence this is your solution.

5/11
Step-by-step explanation:
These are two independent events, because no matter which color the ball picked from jar #1 it will not affect the draw in jar #2.
To evaluate the probability of both balls to be white, we first need to evaluate the probability of each draw resulting in a white ball then multiply those probabilities.
First urn: 10 white, 6 yellow balls
Chances to get a white ball: 10/16, or 5/8.
Second urn: 8 white, 3 yellow balls
Chances to get a white ball: 8 / 11
Chances for both balls to be white:
5/8 * 8/11 = 5/11
