coefficients linear in two variables?

Question

can someone pls answer these.. step by step please

find the general solution

2dx + (2x-y+3)dy = 0 use a change of variable

solve it by coefficients linear in 2 variables

i am on a review because its our quiz tommorow and i am craving to pass that quiz.. i am trying to answer some on my book and but i cant answer this one correctly.. pls help

it is Coefficients that are linear in two variables.. tha's the topic

Answer 1

what is coefficients linear? i've passed differential equation and that doesn't sound familiar

Answer 2

i'm assuming you're speaking in regards to the Pearson Product 2d correlation coefficient, which assumes a linear courting between 2 variables. If the courting is ultimate represented via a curve, then the ability of the courting would be underestimated. frequently situations, nonlinear relationships are plotted on log or log-log scales. this could frequently enable the courting to be plotted as a as we talk line. you could the two rework the values with a functionality or you could look into the values with a particular selection it somewhat is frequently happening to be linear.
