41. Find all solutions to the following equations. Remember to check for extraneous solutions.
1 answer:
Answer:
Ans.
X=3
Step-by-step explanation:
Ok, there are several ways to solve this, I chose the one that can be more visual friendly to you.
SInce the log are based 2, we are going to be using this base on both sides of the equation, so, let Y = (3X+7).
This means.
Since Y = (3X+7)
Therefore X=3
Best of luck.

All we want to do is get an equation with just x on one side and no x's on the other.
We can use inverse operations to accomplish this.
First, bring bx to the left side. Subtract the 3.
Factor ax+bx to x(a+b). (this is pretty much reversing the distributive property)
Divide by a+b and you are left with just x on the left side as 4/(a+b).
