Answer:
x < - 15
Step-by-step explanation:
Given
- 3x - 42 > 3 ( add 42 to both sides )
- 3x > 45
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.
x < - 15
x > -15
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
-3*x-42-(3)<0
Pull out like factors :
-3x - 45 = -3 • (x + 15)
Divide both sides by -3
Remember to flip the inequality sign:
Subtract 15 from both sides
x > -15
