Answer 2

Step-by-step explanation:

2x - 3y + 4 = 0

=} 2x - 3y = -4

=} 2x = -4 +3y

=} x = -4 + 3y

~~~~~~~

2

Now, 2x + 3y + 4 = 0

=} 2 × (-4 + 3) +3y + 4 = 0

~~~~~~~

2

=} -4 + 3 + 3y + 4 = 0

=} 3y = -3

=} y = -3/3

=} y = -1

and,

X = -4 + 3y

~~~~~~~

2

=} -4 +3× (-1)

~~~~~~~

2

=} -4 + (-3)

~~~~~~~~~~

2

=} -4 -3

~~~~

2

=} -7/2

Therefore,

X = -7/2 and y = -1
