Answer:(1,-4)
Step-by-step explanation:
Add 4x to both sides and get
13 = 1 + 3x
12 = 3x [from subtracted 1 from both sides]
x = 4 [from dividing 3 from both sides]
therefore your answer would be x = 4

We can do this problem using two ways....
Let me show you both methods.
<u>Method 1: "Without using logs"</u>
Now, since both sides of the equation have same base and they equal each other, then their exponent must be equal to each other. So, we equal their exponents.
After equaling the exponents, we get,

Now,
<u>Method 2: "Using Logs"</u>
<u>So, either way we get x= 6</u>
The 8 is a, the 3 is b and -45 is c
Plug them into the quadratic formula
