4x - 3y + 0= 0--------(1)
2x + 3y - 18 = 0 ------(2)
x/{ (-3)×(-18) -3×0} = -y/{ 4×(-18) -2×0} = 1/{4×3 + 2×3}
x/54 = -y/-72 = 1/18
x/54 = y/72 = 1/18
x = 54/18 =3
y = 72/18 = 4
2x + 3y - 18 = 0 ------(2)
x/{ (-3)×(-18) -3×0} = -y/{ 4×(-18) -2×0} = 1/{4×3 + 2×3}
x/54 = -y/-72 = 1/18
x/54 = y/72 = 1/18
x = 54/18 =3
y = 72/18 = 4
kradha:
the answer is
something else
how u got 2x+3y-2
it will be -18
2x +3y = 2 => 2x + 3y -2 = 0
it is 2x+3y=18 c d qu properly
now see answer !!!
