-3u < with a line - 12

1 answer

To solve this inequality, we can start by isolating the variable by moving all the terms involving u to one side of the inequality and the constant term to the other side.

-3u < -12

To move -3u to the right side, we need to divide both sides of the inequality by -3. However, when dividing or multiplying an inequality by a negative number, the direction of the inequality sign needs to be reversed. So, we have:

u > -12 / -3

Simplifying the right side gives:

u > 4

Therefore, the solution to the inequality -3u < -12 is u > 4.
