# 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
