Question

Complete the equation so it has no solution. 9x - 7x + 5 = ___ - 7

Answer 1

Answer: 2x

Step-by-step explanation: The answer is 2x, because on the LHS, 9x - 7x = 2x, so the LHS is 2x + 5, if we make the RHS 2x - 7, the equation will become 2x + 5 = 2x - 7, this makes the equation unsolvable
