Step-by-step explanation:

1) -5x<35

we divide both sides by 5

-5x/5<35/5

-x<7

we divide both sides by-1 to remove the negative sign

-x/-1<7/-1

x<7/-1

2) 2x>-42

we divide both sides by 2

2x/2>-42/2

x>-21

3) x/3≤-7

we multiply by 3 and we cancel 3

3(x/3)≤3(-7) we cancel the 3

x≤-21

4) x/-4≥-4

we do the same thing

x≥1
  • -5x<35
  • -x<7
  • x>7

Solution set (7,oo)

#2

  • 2x>-42
  • x>-21

Solution set (-21,oo)

#3

  • x/3≤-7
  • x≤-21

Solution set (-oo,-21]

#4

  • x/-4≥-4
  • x≤16

Solution set (-oo,16]
