Answer:
x= -8
Step-by-step explanation:
x-89=7(2x+3)-6 distribute 7
x-89=14x+21-6 add like terms
-13x=104 divide
x=-8
The answers are x=6 or x=-1.
To solve this, we first use the quotient rule for the natural logarithm. It says that ln(x/y) = ln(x) - ln(y). Applying this, we take our original equation,

and rewrite it as

We undo natural log by raising e to both sides:

Once this is canceled we are left with:

If we view this as a proportion, we can cross multiply:
(x-3)(x) = 2(x+3)
Using the distributive property on both sides we have:
x²-3x=2x+6
Cancel the 2x from the right hand side by subtracting:
x²-3x-2x=2x+6-2x
x²-5x=6
Cancel the 6 by subtracting:
x²-5x-6=0
This is easily factorable. We want factors of -6 that sum to -5; -6(1) = -6 and -6+1=-5:
(x-6)(x+1)=0
Using the zero product property, we know either x-6=0 or x+1=0; thus x=6 or x=-1.
The answer is C. 51/4. Hope I helped!
Since they are vertical they are equal to each other.
3x + 4 = 7x - 9
4 = 4x - 9
13 = 4x
3.25 = x
So the value of x is 3.25.
Hope this helps :)
Answer:
Answer is 81.
Step-by-step explanation:
Given two expressions are
and 
Now we divide first expression by the second.


Therefore 81 is the answer.
