Question

РЕШИТЕ УРОВНЕНИЯ 3+(2x+3)^2=4(x-6)(6+x) 6-x+(2x-1)^2=4(x+3)^2 39x+(4x+3)^2=2+4(2x+1)^2

Answer 1

) x : (2 1/3) = 9,2 : 2,3

x : (7/3) = 4

x = 4 * 7/3 = 28/3 = 9 1/3

2) 7,2 : 2,4 = x : (4 1/3)

3 = x : (13/3)

x = 3 * 13/3 = 13

3) (4 2/7) : (2 1/7) = 3,2 : x

(30/7) : (15/7) = 2 = 3,2 : x

x = 3,2 : 2 = 1,6
