Question

Which linear equation has no solution? 5x+12=5x−7

Answer 1

Trying to solve this leads to an absurdity, so No Solution.

Explanation:

5x+12=5x−7

Lets attempt to solve:

Subtract 5x from both sides

5x - 5x + 12 = 5x - 5x - 7

0 + 12 = 0 - 7

12 = -7

This is absurd so there is no solution.
