Question

3(5-2x)=-4(cx+4)

What value for c in the equation above will make the equation have no solutions?

Answer 1

c = 3/2

Explanation:

hello :

3(5-2x)=-4(cx+4)

-6x+15 = - 4 cx-16

-6x+4cx = -16-15 means 6x-4cx=-31

(6-4c ) x = 31

the equation have no solutions when : 6-4c = 0 (you have : 0x=31...false)

-4c=-6

c= -6/-4

c = 3/2
