Question

Which equation has no solution?

Answer 1

Answer:

C

Step-by-step explanation:

$A. 20 - 6x = 4(1-x) -4 \\=>20 - 6x = 4-4x -4\\=>20-6x=-4x\\=> 20=2x\\=> x=10$

$B. 6x-2x = 4(1-2)+4\\=> 4x = 4(-1) +4\\=> 4x =0\\=>x=0$

$C.2x-6x=4(1-x)+4\\=> -4x = 4 - 4x +4\\=>-4x + 4x = 8\\=> no solution$

$D.6x-2x =4(1-2) +4\\=> 4x = 4(-1) +4\\=> 4x = 0\\=> x=0$
