Question

which of the following pair of linear equations are parellel
a)2x+3y+5=0
3x+2y-5=0
b)x-y-10=0
2x-2y+15=0
c)2x+5y+2=0
4x-10y+4=0
d)x-y=10
x+y=10
​

Answer 1

Answer:

OPTION D IS THE FAIR OF LINEAR EQUATION

Answer 2

B is the correct option cuz for linear equations to be parallel their x and y coefficient should be equal
So when u divide 2x-2y+15 u get x-y+15
(Equal coefficient 1 and -1 )
