Quadrilateral abcd is a parallelogram if one pair of opposite sides is both equal and parallel. prove that quadrilateral abcd is a parallelogram by finding the value of x.
a) x = -3
b) x = -5
eliminate
c) x = -7
d) x = -
17
3

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

i honestly dont know
