Question

помогите решить 1348 номер

Answer 1

4,6/(х+4,4)=8,4/(3х+5,1)
4,6(3х+5,1)=8,4(х+4,4)
13,8х+23,46=8,4х+36,96
5,4х=13,5
х=2,5

2 2/3(х-1 1/8)=1 1/2(х+1/3)
8/3х-8/3*9/8=3/2х+3/2*1/3
8/3х-3/2х=3+1/2
10/6х=7/2
х=7/2*6/10
х=2,1 или 21/10

Answer 2

А)4.6(3х+5.1)=8.4(х+4.4)
13.8х+23.46=8.4х+36.96
5.4х=13.5
х=2.5
