The solution of the equation ax + b = 0 is
(a) a/b
(b) -b
(c) -b/a
(d) b/a

Solution:

The given equation is ax + b = 0

Thus,

ax = - b

x = - b/a

Hence the correct option is (c) - b/a

✦ Try This: The solution of the equation ax - b = 0 is (a) a/b, (b) -b, (c) -b/a, (d) b/a

The given equation is ax - b = 0

Thus,

ax = b

x = b/a

Hence the correct option is (d) b/a
