-90=2x+2(5x-9)

- 90 = 2 x + 2 (5 x - 9)

x = - 6

Solution steps

- 90 = 2 x + 2 (5 x - 9)

Switch sides

2 x + 2 (5 x - 9) = - 90

Expand

2 (5 x - 9) : 10 x - 18

2 x + 10 x - 18 = - 90

Add similar elements:

2 x + 10 x = 12 x

12 x - 18 = - 90

Move

18

to the right side

12 x = - 72

Divide both sides by

12

x = - 6

x^{2} (x^{2} - 1) \geq 0

4 - (x - 5) = - 18 + 2 x

25 + \frac{36}{1 + 0.6 ( 0.7 ) ^{- 100}}

∣ p ∣ - 3 \leq 0

\frac{1}{10} x + \frac{9}{10} = 5
