Solution

x \geq 10

+1

Interval Notation

[10, \infty)

Solution steps

2 (x + 9) \leq 4 x - 2

Expand

2 (x + 9) : 2 x + 18

2 x + 18 \leq 4 x - 2

Move

18

to the right side

2 x \leq 4 x - 20

Move

4 x

to the left side

- 2 x \leq - 20

Multiply both sides by

- 1

2 x \geq 20

Divide both sides by

2

x \geq 10
