Solve the following inequality for x.

ax - 3 < 17

1 answer

To solve the inequality \( ax - 3 < 17 \), follow these steps:

  1. Add 3 to both sides of the inequality: \[ ax < 17 + 3 \] \[ ax < 20 \]

  2. Now, divide both sides by \( a \). Note that the direction of the inequality will change if \( a < 0 \):

    • If \( a > 0 \): \[ x < \frac{20}{a} \]
    • If \( a < 0 \): \[ x > \frac{20}{a} \]
    • If \( a = 0 \), the inequality \( -3 < 17 \) is always true, meaning \( x \) can be any real number.

So, the solution to the inequality depends on the value of \( a \):

  • If \( a > 0 \): \[ x < \frac{20}{a} \]

  • If \( a < 0 \): \[ x > \frac{20}{a} \]

  • If \( a = 0 \): \[ x \text{ is any real number.} \]
