Find and correct the error.

x/4 + 6 > 3
x + 6 > 12
x > 6

1 answer

Let's find and correct the error in your inequality steps.

Starting from the original inequality:

  1. Start with: \[ \frac{x}{4} + 6 > 3 \]

  2. Subtract 6 from both sides: \[ \frac{x}{4} > 3 - 6 \] \[ \frac{x}{4} > -3 \]

  3. Multiply both sides by 4 (Note: since we are multiplying by a positive number, the direction of the inequality remains the same): \[ x > -3 \cdot 4 \] \[ x > -12 \]

The error occurred in the second step where it incorrectly jumped to \( x + 6 > 12 \).

Thus, the correct final result is: \[ x > -12 \]
