x-0.1x=8.1x

x - 0.1 x = 8.1 x

x = 0

Solution steps

x - 0.1 x = 8.1 x

Add similar elements:

x - 0.1 x = 0.9 x

0.9 x = 8.1 x

Multiply both sides by

10

9 x = 81 x

Move

81 x

to the left side

- 72 x = 0

Divide both sides by

- 72

x = 0

x, \frac{x}{y} = 4

4 x (7 x - 5) - 7 x (4 x - 2) = - 12

a = (x - 2)^{2} + (x + 3)^{2} - 2 (x + 1) (x - 1)

2 x + 3 = \frac{x}{2} - 1

x + 1 = (2^{8} mod 7)
