Please help me solve by substitution thanks rob.

4X + 2y = 3
y = -X
here we have y = -x
now substitute the value y = -x in the first equation
==> 4x + 2 (-x) = 3
==> 4x -2x = 3
==> 2x = 3
==> 2x/2 =3/2
==> x = 3/2

now we have the value x = 3/2
now substitute the value x =3/2 in the second equation, y = -x
==> y = -3/2
BYE!!!!!!!!!
