Solve for v. 19v – 18 = 16 + 17v

GarryVolchara [31]

Answer:

v= 17

Step-by-step explanation:

Start with the given equation.

19v – 18 = 16 + 17v

Move -18 to the other side, and swap it's sign.

19v = 16 + 18 + 17v

Move 17v to the other side and swap it's sign.

19v - 17v = 16 + 18

Combine like terms.

2v = 34

Divide by 2v.

v = 17

If ex + e*-1= 2, then x =..

lianna [129]

Note: Your equation seems a little unclear. But, I am assuming that your equation is:

$e^x\:+\:e^{-1}=\:2$

Because my solution would still clear your concept about this topic, no matter what the question is.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

$e^x\:+\:e^{-1}=\:2$

subtract $e^{-1}$ from both sides

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

$e^x=2-\frac{1}{e}$

$\ln \left(e^x\right)\:=\ln \:\left(2-\frac{1}{e}\right)$

$\:x\cdot ln\left(e\right)=\ln \:\:\left(2-\frac{1}{e}\right)$

$\:x\cdot 1=\ln \:\left(2-\frac{1}{e}\right)$ ∵ $\:\:\ln \left(e\right)=1$

$x=\ln \:\left(2-\frac{1}{e}\right)$

$x=0.5$
