Answer:

This is a no solution (if you're asking to solve this equation). It will lead to:

20 = 12

Which is NOT equal.

The answer is thus No Solution.

Step-by-step explanation:

4(x + 5) = 4(3 + x) ~ Distribute it

4x + 20 = 12 + 4x ~ Subtract the x

20 = 12 ~ Remaining

20 does NOT equal 12.

The answer is No Solution.

What is the value of x in the equation below?

denis23 [38]

Answer:

Step-by-step explanation:

Alright, lets get started.

The given equation is :

$1+2e^{x+1}=9$

Subtracting 1 in both sides

$1+2e^{x+1}-1=9-1$

$2e^{x+1}=8$

Dividing 2 in both sides

$e^{x+1}=\frac{8}{2}$

$e^{x+1}=4$

Taking log on both sides

$loge^{(x+1)}=log4$

$(x+1)loge=log4$

Plugging the value of log e as 1

$x+1=log4$

$x=log4-1$ ..................... Answer

Hope it will help :)
