What does m equal in this equation 5m – 8 = 3m + 8 for m.

6+8x-9=11x+14-3x, can this equation be always, sometimes, or never true.
goblinko [34]
To answer the question above, simplify both sides of the equation. This gives,
                         8x - 3 = 8x + 14
Next, cancel the term 8x because it appears on both sides of the equation giving,
                             -3 = 14
That is NOT true. Therefore, the answer is the equation is NEVER TRUE.
