Question

ax + b = 0 for x

Answer 1

To solve the equation ax + b = 0 for x, we need to isolate x on one side of the equation.

We can begin by subtracting b from both sides of the equation:

ax + b - b = 0 - b

This simplifies to:

ax = -b

To isolate x, divide both sides of the equation by a:

ax/a = -b/a

The a's in the numerator and denominator cancel out, leaving:

x = -b/a

So, the solution to the equation ax + b = 0 for x is x = -b/a.
