Solution steps

- 3 (7 x + 1.4) - 7.9 = x

Expand

- 3 (7 x + 1.4) - 7.9 : - 21 x - 12.1

- 21 x - 12.1 = x

Move

12.1

- 21 x = x + 12.1

Move

x

to the left side

- 22 x = 12.1

x = - 0.55

x^{2} + 4 x = 7

10 x - 4 \geq 10 x - 7 or 7 - 7 x \geq - 4 x + 4

8 ∣ - 4 + 3 n ∣ - 2 = 14

\frac{( 7 + 2 i ) ( 8 - i )}{2 + i}

x^{2} x^{\frac{1}{2}}
