3(-6+6x)=18

multiply the bracket by 3

(3)(-6)=-18

(3)(6x)=18x

-18+18x=18

move -18 to the other side

sign changes from -18 to +18

-18+18x+18=18+18

-18+18+18x=18+18 ( rearranging)

18x=36

divide both sides by 18 to get x by itself

18x/18=36/18

answer:

x=2

You multiply the 3 by -6 then multiply the 3 by 6 , one you get -18 and the other you 18x you change the -18 into a positive then add it by 18 in get 36 then you divide by 18x in get 2

Solve the differential equation dy/dx+4xy=x

Irina-Kira [14]

$\dfrac{\mathrm dy}{\mathrm dx}+4xy=x$
$\dfrac{\mathrm dy}{\mathrm dx}=x(1-4y)$

This ODE is separable, so you can write

$\dfrac{\mathrm dy}{1-4y}=x\,\mathrm dx$

Integrating both sides gives

$-\dfrac14\ln|1-4y|=\dfrac12x^2+C$
$\ln|1-4y|=-2x^2+C$
$1-4y=e^{-2x^2+C}$
$1-4y=Ce^{-2x^2}$
$y=\dfrac{1-Ce^{-2x^2}}4$

Answer:

What's the question here?
