16-2r=-3r+6r+1

16 - 2 r = - 3 r + 6 r + 1

r = 3

Solution steps

16 - 2 r = - 3 r + 6 r + 1

Add similar elements:

- 3 r + 6 r = 3 r

16 - 2 r = 3 r + 1

Move

16

to the right side

- 2 r = 3 r - 15

Move

3 r

to the left side

- 5 r = - 15

Divide both sides by

- 5

r = 3

2 x^{2} - x - 1

x - 1 \leq 2 and x + 2 \geq 4

19 \cdot 3

x^{2} - 16 x + 48 = 0

x^{2} - 16 x + 64 \geq 0
