Question

Решить уравнение 1). (x-6)^2=(x-3)^2. 2) 6x-4-5x=2. 3). 6x-1/2-x=3

Answer 1

1)x^2 - 12x + 36 = x^2 - 6x + 9

x^2 - x^2 - 12x + 6x + 36 - 9 = O

-6x + 27 = O

-6x = - 27

x = 4.5

2)6x-4-5x = 2

x-4 = 2

x = 2+4

x = 6

3)6x - 1/2 - x = 3

5x = 3+ 1/2

5x = 3 + 0.5

5x = 3.5

x = 3.5 : 5

x = 0.7
