7w-3(4w+8)=11

7 w - 3 (4 w + 8) = 11

w = - 7

Solution steps

7 w - 3 (4 w + 8) = 11

Expand

- 3 (4 w + 8) : - 12 w - 24

7 w - 12 w - 24 = 11

Add similar elements:

7 w - 12 w = - 5 w

- 5 w - 24 = 11

Move

24

to the right side

- 5 w = 35

Divide both sides by

- 5

w = - 7

8 x^{- 2}

\frac{3}{4} x - 2 x \leq 1 + 2

4 {x - (3 x - 2)} > 3 (x + 5) - 15

8 x^{2} + 21 = - 59 x

- x^{2} - 5 x + 6 = 0
