Answer 1

Multiplying both sides of this equation by 3, to eliminate the fraction, we get:

9 + m = 6.

Next, we subtract 9 from both sides to isolate m:  m = 6 - 9 = -3

Then m = -3.

Check:  Subst. -3 for m in this equation:

9 - 3       6

------- = ------ = 2 (as expected).  Thus, m = -3 is correct.

  3          3

Problem #10:

4n - 9 = -9     Add 9 to both sides:  4n = -9 + 9 = 0.

Divide both sides by 4:  n = 0.

Check:  Substitute 0 for n:  4(0) - 9 = -9  is true.
