Answer:

x=−6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x−7-2/3(9x−6)=15

3x+−7+−6x+4=15(Distribute)

(3x+−6x)+(−7+4)=15(Combine Like Terms)

−3x+−3=15

−3x−3=15

Step 2: Add 3 to both sides.

−3x−3+3=15+3

−3x=18

Step 3: Divide both sides by -3.

−3x/−3=18/−3

x=−6

What is the value of x in the equation below?

belka [17]

$remember$
$ln(a^b)=bln(a)$
$ln(e)=1$
$so$
$ln(e^x)=xln(e)=x$

$1+2e^{x+1}=9$
$minus \space\ 1 \space\ both \space\ sides$
$2e^{x+1}=8$
$divide \space\ both \space\ sides \space\ by \space\ 2$
$e^{x+1}=4$
$take \space\ ln \space\ of \space\ both \space\ sides$
$ln(e^{x+1})=ln(4)$
$(x+1)ln(e)=ln(4)$
$x+1=ln(4)$
$minus \space\ 1 \space\ from \space\ both \space\ sides$
$x=ln(4)-1$
$answer \space\ is \space\ C=ln(4)-1$
