Answer:
X = 16
Explanation:
Hi again.
To solve this equation, use the logarithm property of equality to rewrite log7 (3x + 1) = 2 as 3x + 1 = 7^2.
We can then solve for x by subtracting 1 from both sides, giving us 3x = 7^2 - 1, then dividing both sides by 3 to get x = (7^2 - 1)/3.
Therefore, the solution is x = (7^2 - 1)/3.
So now, x will be 16.
Hope that can help :)
