Question

Which of the following equations has an infinite solution set?

A: 3(4x-2)= 6(2x-1)
B: 3(x-2)=8+3x
C: 2(x+8)= 4(x+2)
D: (x+2)/3= 2x-1

Answer 1

It's A.

Explanation:

A. 3(4x - 2) = 6(2x - 1)

Applying the Distributive Law:

12x - 12 = 12x - 12

We see that the left side of the equation equals the right side. this is an identity and we can assigned any value we like to x.

This means that there are infinite solutions to equation A.
