Final answer:
When given the equation ax - b = 0 and a is not equal to zero, the solution for x is x = b/a, which is obtained by first adding b to both sides, then dividing by a.
Step-by-step explanation:
If we have the equation ax - b = 0 and a ≠ 0, then in order to solve for x, we need to isolate x on one side of the equation. First, we would add b to both sides of the equation to get ax = b. Next, we would divide both sides by a (since it is not zero) to solve for x. The result is x = b/a.
Therefore, x = b/a is the correct solution when you are given an equation of the form ax - b = 0 and a ≠ 0.
