Question

Which linear equation has no solution?

3/2 (9x +6) 3
5x + 12 = 5x -7
4x + 7 = 3x + 7
-3(2x - 5) = 15 - 6x

Answer 1

9514 1404 393

Answer:

5x + 12 = 5x - 7

Explanation:

There will be no solution when the coefficients of x are the same on both sides of the equal sign and the constants are different. That is the case for ...

5x + 12 = 5x - 7

This reduces to ...

19 = 0 . . . . . no value of x will make this be true: NO SOLUTION
