8x+5(-4x)=24

8 x + 5 (- 4 x) = 24

x = - 2

Solution steps

8 x + 5 (- 4 x) = 24

Remove parentheses:

(- a) = - a

8 x - 5 \cdot 4 x = 24

Multiply the numbers:

5 \cdot 4 = 20

8 x - 20 x = 24

Add similar elements:

8 x - 20 x = - 12 x

- 12 x = 24

Divide both sides by

- 12

x = - 2

- 9 = - 11 + \frac{b}{8}

5 x^{2} - 6 \geq 14

(4 a - 8)^{2} = - 64

\frac{21 5}{- 7 125}

- 7 + 6 ∣ 3 x - 9 ∣ = - 61
