8x - (5x + 4) >= -31 ... Start with the given inequality.


8x - 5x - 4 >= -31 ... Distribute


3x - 4 >= -31 ... Combine like terms.


3x - 4 +4 >= -31 +4 ... Add 4 to both sides.


3x >= -27 ... Combine like terms.


3x/3 >= -27/3 ... Divide both sides by 3 to completely isolate x.


x >= -9 ... Reduce
