 Given \: 3 - x \lt 4x - 12

/* Add bothsides of the equation by 12 ,we get */

 \implies 3 - x + 12 \lt 4x - 12 + 12

 \implies  - x + 15 \lt 4x

/* Add bothsides of equation by x , we get */

 \implies  - x + 15 + x  \lt 4x + x

 \implies   15   \lt 5x

/* Dividing bothsides by 5, we get */

 \implies   \frac{15}{5}   \lt x

 \implies 3 \lt x

 \implies x \gt 3

Therefore.,

 \green {  x \gt 3}
