Answer:
see explanation
Step-by-step explanation:
1
6 = 3x - 9 ( add 9 to both sides )
15 = 3x ( divide both sides by 3 )
5 = x
2
x + 4 < 1 ( subtract 4 from both sides )
x < - 3
3
[tex]\frac{x}{2}[/tex] + 3 = - 5
Multiply terms on both sides by 2
x + 6 = - 10 ( subtract 6 from both sides )
x = - 16
