Question

Which of these equations has NO solution? A. 3 ( 2 x + 7 ) = 6 ( x + 4 ) − 3 B. 3 ( 6 x − 5 ) = 3 ( 6 x − 5 ) + x C. 8 ( x − 3 ) + 14 = 2 ( 4 x + 5 ) D. 13 x − 7 = 12 ( x − 1 ) + x + 5

Answer 1

B ig

Explanation:

A: 3(2x+7) = 6(X+4) - 3

<=> 6x+ 21 = 6x + 24 - 3 = 6x + 21

<=> 0 = 21 - 21 = 0

B: 3(6x-5)= 3(6x-5)+x

<=> 18x-15= 18x - 15 + x = 19x - 15

<=> 0 = x

C: 8(x-3) + 14= 2(4x+5)

<=> 8x - 24 + 14 = 8x - 10 = 8x + 10

<=> 0 = 0

D: 13x - 7 = 12( x - 1) +x + 5

<=> 13x - 7 = 12x -12 + x + 5 = 13x - 7

<=> 0 = 0
