Solve the absolute value equation.<br>12 + 2x[ = [x - 6]​
Tom [10]

Answer:

x=−18

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

12+2x=x−6

12+2x=x+−6

2x+12=x−6

Step 2: Subtract x from both sides.

2x+12−x=x−6−x

x+12=−6

Step 3: Subtract 12 from both sides.

x+12−12=−6−12

x=−18

Solving Exponential and Logarithmic Equations In Exercise, solve for x.<br> 2 In x + In(x - 2) = 0
Pani-rosa [81]

Answer:

The value of x is about 2.206.

Step-by-step explanation:

Consider the given equation is

2\ln x+\ln (x-2)=0

We need to find the value of x.

Using the properties of logarithm we get

\ln x^2+\ln (x-2)=0            [\because \ln a^b=b\ln a]

\ln (x^2(x-2))=0             [\because \ln (ab)=\ln a+\ln b]

\ln (x^2(x-2))=ln 1              [\because \ln 1=0]

On comparing both sides we get

x^2(x-2)=1

x^3-2x^2=1

Using graphing calculator, the real solution of the above equation is

x\approx 2.206

Therefore, the value of x is about 2.206.
