0.4 x = 2 x + 1.2

x = - \frac{3}{4}

Decimal Notation

x = - 0.75

Solution steps

0.4 x = 2 x + 1.2

Multiply both sides by

10

4 x = 20 x + 12

Move

20 x

to the left side

- 16 x = 12

Divide both sides by

- 16

x = - \frac{3}{4}

(1 6^{\frac{3}{2}})^{\frac{1}{2}}

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

m^{2} - 8 m - 1008

6 x^{2} + 2 = 13 x

- x = 0.33 (1 + 9.68 x)
