x < –7

Sagot :

Answer:

[tex]\boxed{\boxed{\sf x>-7}}[/tex]

Step-by-step explanation:

[tex]\sf -5x-7<28[/tex]

Add 7 to both sides:

  • [tex]\sf -5x-7+7<28+7[/tex]
  • [tex]\sf -5x<35[/tex]

Multiply both sides by -1:

  • [tex]\sf \left(-5x\right)\left(-1\right)>35\left(-1\right)[/tex]
  • [tex]\sf 5x>-35[/tex]

Divide both sides by 5:

  • [tex]\sf \cfrac{5x}{5}>\cfrac{-35}{5}[/tex]
  • [tex]\sf x>-7[/tex]
