Question

A pair of opposite angles of a parellelogram are 40x and 50y .write a linear equation which satisfies this data.

Answer 1

40x=50y. = 40x-50y=0

Answer 2

Opposite angkes of a parallelogram are equal. So the required equation will be:
40x =50y
Therefore, 40x-50y=0 is the required linear equation

Hope this helps :)
