What is the value of the variable? 3(x- 2)=15
STatiana [176]

Answer:

x=7

Step-by-step explanation:

To solve for x, you have to multiply the terms in parenthesis by 3. Then you add 6 to each side of the equal sign. Then you divide each side of the equal sign by 3 to get x=7

3x-6=15\\3x=15+6\\3x=21\\x=21/3\\x=7

Neporo4naja [7]

Answer:

its B

The solution to the equation log2x + log2(x – 6) = 4 is x =
GenaCL600 [577]

Answer:

Value of x=8

Step-by-step explanation:

Given : log_2x+log_2(x-6)=4          

To find : The solution to the equation given

Solution :

Step 1- Write the given expression

log_2x+log_2(x-6)=4  

Step 2 - Using logarithmic laws

log_{b}x+log_by=log_bxy

log_2(x)(x-6)=4  

Step 3 - To remove log-base 2, we need to raise the left and right hand terms to power 2.

(x)(x-6)=2^4  

x^2-6x-16=0  

Step 4 - Solve the quadratic equation

x^2-8x+2x-16=0  

x(x-8)+2(x-8)=0  

(x-8)(x+2)=0  

Either x=8 or x=-2

We neglect x=-2 because negative value is not defined in log.

Value of x=8
