Question

The sum of nine times a number and fifteen is less than or equal to the sum of twenty four and ten times the number

Answer 1

The inequality to represent that would be 9x + 15 ≤ 10x + 24

Answer 2

9n+15≤10n+24  subtract 15 from both sides

9n≤10n+9  subtract 10n from both sides

-n≤9  divide both sides by -1 and reverse inequality sign because of division by a negative value...
