y=13.75
Step-by-step explanation:
5x+3(-3x-2)=15
5x+-9x+-6=15
-4x+-6=15
-4x+-6+6=15+6
-4x=21
Answer:
To solve this, we will need to use log properties. We know that subtracting two log equations gives us:
If log base 10 equals 2, we know that equals 100. We can solve this by:
= 100
5x³=100x²
x³= 20x²
x³-20x²=0
x²(x-20)=0
Thus, the answer is x=20.
