4x-2y=14

Blababa [14]

4x - 2y = 14
y = 0.5x -1

Get just one variable on one side for both equations.

4x - 2y = 14 ⇒ 4x = 2y + 14 ⇒ 4x - 14 = 2y
y = 0.5x - 1 ⇒ x - 2 = 2y

Use the transitive property and then solve for x.

x-2 = 4x-14
12 = 3x
x = 4

Edit: Apprently I didn't use substitution. Oops! Sorry...

How to solve: dy/dx=e^(x-y), y(0)=ln3

ella [17]

Hello,

$\dfrac{dy}{dx} = \dfrac{e^x}{e^y} \\

e^y*dy=e^x*dx \\

e^y=e^x+C\\

if\ x=0\ then\ y=ln(3) ==\ \textgreater \ 3=1+C==\ \textgreater \ C=2\\

\boxed{y=ln(2+e^x)}\\
