Question

Select the correct answer.

Which equation has no solution?
A.
2.3y + 2 + 3.1y = 4.3y + 1.6+ 1.1y + 0.4

B.
32x + 25 - 21x = 10x

C.
5/8x + 2..5 = 3/8x + 1.5 + 1/4x

D.
1/3 + 1/7y = 3/7y

Answer 1

Equation C: 5/8x + 2..5 = 3/8x + 1.5 + 1/4x

Explanation:

Let us go through each of the equations one by one.

Equation A:

This simplifies to

which has infinitely many solutions.

Equation B:

this simplifies to

which is exactly one solution.

Equation C:

this simplifies to

There's no way this is going to be possible; this equation has no solutions.

Equation D:

this gives

which is exactly one solution.

Thus we see that it is equation C that has no solutions. I know that this is VERY late but I hope that it helps others. ^-^
