Question

Which of the following equations has infinite solution?

A. 1/5x+10 =2(1/10x+20)
B. 1/4x -2= -1/2(4 -1/2x)
C. 1/3x + 12 =5(1/3x +12)
D. 1/2x - 6= - 1/5(30 -10x)
Been stuck on this for a while can someone help

Answer 1

A)
`1/5x + 10 = 2(1/10x+20) =` no solution

B)
`1/4x - 2 = -1/2(4-1/2x) =` infinite solutions

C)
`1/3x + 12 =5(1/3x +12) =` x = -36

D)
`1/2x - 6= - 1/5(30 -10x) =` x = 0


`\fbox {B)}` has infinite solutions, which is your answer.
