Question

Classify the equation, 9x + 4 = 9x - 8, as having one solution, no solution, or infiinitely many solutions.

Answer 1

no solution

Explanation:

Given

9x + 4 = 9x - 8 ( subtract 9x from both sides )

9x - 9x + 4 = - 8 ( subtract 4 from both sides )

0 = - 12 ← this is not possible, hence

The equation has no solutions
