4(x + 6) > −5(x + 5) − 14 ​ ​Given

(4)(x) + (4)(6) > (-5)(x) + (-5)(5) - 14

​​4x + 24 > −5x − 25 − 14 Distributive property ​

4x + 24 > -5x - (25 + 14)

4x + 24 > −5x − 39 ​ Simplify right side

4x + 24 + 39 > -5x -39 + 39

4x + 63 > −5x Addition property of equality

4x - 4x + 63 > -5x - 4x

​ 63 > −9x ​ Subtraction property of equality

63 : (-9) < -9x : (-9) /-9 < 0 → switch the signs/

−7 < x Division property of equality
