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
