Question

HELPPP ASAPPP! PLZ

Which system has no solution?
A.4y = 2x – 6

B.3x + 5y = 7
4x = 2y – 5

C.2y = 4x + 2

D.2x = 5y + 4
15y = 6x – 12

Answer 1

Answer : D

2x=5y+4

15y=6x-12

Solve 2x=5y+4 for x

Divide both sides by 2

2x/2=(5y+4)/2

x = 5/2 y +2

Substitute 5/2 y +2 for x in 15y=6x-12

15y= 6x-12

15y= 6(5/2 y +2 ) -12

Simplify both sides of the equation

15y=15y

Add -15y to both sides

15y-15y= 15y-15y

0=0
