Question

Which of the following systems of equations has no solution?

a. 18x − 6y = 14; 3y = 9x − 7
b. 7x − 4 = 3y; 6y − 3 = 14x
c. 4x + y = 10; 2y = 8x − 2
d. -5y = x − 6; 3x − 15y = 9

Answer 1

Try B...

Answer 2

@matricked : is it B ?

Answer 3

YUP

Answer 4

7x - 3y = 4

Multiply it by 2,

14x - 6y = 8
14x - 6y = -3

When you subtract them both x and y will get cancel..

Answer 5

these two equations represent non overlapping paralel lines hence they do not intersect so no solution
