Answer: x < 5/3

Explanation:

-(4x + 20) < −7(x + 15/7) ............................ Question

-4x - 20 < -7(x + 15/7) ................................ Distribute

-4x - 20 < -7x - 15 ...................................... Distribute

-4x - 20 + 20 < -7x - 15 + 20 ................... Add 20 to both sides

-4x < -7x + 5 ............................................... Simplify

-4x + 7x < -7x + 5 + 7x ............................. Add 7x to both sides

3x < 5 .......................................................... Simplify

3x / 3 < 5 / 3 .............................................. Divide both sides by the same factor

x < 5/3 ......................................................... Simplify
