when taking a fraction and making it a mixed number, you divide the numerator by the denominator. whatever you have left after dividing is your numerator, and denominator stays the same. hope this helps!

How do you solve 2/3 x=12 one step

asambeis [7]

Remembe you can do anything to an equation as long as you do it to both sides

multiply both sides by 3/2 or divide both sides by 2/3 (same thing)
we get x=36/2 or x=18

Solve the differential equation dy/dx=2*y/x,x>0 simplify?

Andrew [12]

Separate your variables:

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{2y}x\implies \dfrac{\mathrm dy}y=2\dfrac{\mathrm dx}x$

Integrating both sides gives

$\displaystyle\int\frac{\mathrm dy}y=2\int\frac{\mathrm dx}x\implies \ln|y|=2\ln|x|+C\implies y=e^{2\ln|x|+C}=Cx^2$
