Question

Xy + 4x = 3+2xy? Can you show how to olve problem?

Answer 1

xy + 4x = 3 + 2xy

xy - 2xy + 4x = 3

-xy + 4x = 3...equation a;

-x(y - 4) = 3

y - 4 = -3/x

y = -3/x + 4

take y and replace into eq. a;

-x(-3/x + 4) + 4x = 3

3 - 4x + 4x = 3

3 = 3

x is infinity??

Answer 2

xy + 4x = 3 + 2xy

subtract 2xy from both sides

-2xy+(xy+4x)=(3+2xy)-2xy

4x - xy = 3

x(4-y) =3

divide both sides by (4-y)

x = 3/(4-y)
