To evaluate 1/a + 1/b when a=4 and b=-3, we substitute the values into the equation:
1/a + 1/b = 1/4 + 1/-3
To simplify, we find a common denominator, which is 12:
1/a + 1/b = 3/12 - 4/12
Next, we subtract the two fractions:
1/a + 1/b = (3-4)/12
1/a + 1/b = -1/12
Therefore, when a=4 and b=-3, 1/a + 1/b = -1/12.
1/a + 1/b = 1/4 + 1/-3
