Question

Represent 3x (-5) and 5 x (-3) on the number line.​

Answer 1

1 ) 3x - 7 < 5 + x

3x - x < 5 + 7

2x < 12

x < 12/2

x < 6

draw x = 6 line on a graph .

and shade the region x < 6 which is shown in

the graph red color.

2 ) 11 - 5x ≤ 1

- 5x ≤ 1 - 11

- 5x ≤ - 10

divide bothsides with - 5 , we get

( - 5x )/( - 5 ) ≥ ( - 10 )/( - 5 )

x ≥ 2

draw a line x = 2 , and shaded region which

shown in black lines .

I hope this helps you.
