Methods of solving first order first degree differential equations

Question

$The substation required to change (3 y - 7 x + 7) d x + (7 y - 3 x + 3) d y = 0 to a homogeneous differential equation is$

Moderate

A

$x = X + 2 y = Y + 2$
B

$x = X, y = Y + 1$
C

$x = X + 1, y = Y + 1$
D

$x = Y + 1, y = Y$

Solution

$\begin{array}{l} Point of intersection of (3 y - 7 x + 7) = 0 and (7 y - 3 x + 3) = 0 \\ Is (h, k) = (1, 0) \end{array}$
