Question

Решите уравнение :
5,6:х+0,16=0,3 
4,13-1,7Х=4,028
64:(2,4у+19,04)=3,2

Answer 1

$1 \ 5.6:x+0.16=0.3 \ 5.6:x=0.3-0.16 \ 5.6:x=0.14 \ x=5.6:0.14 \ x=40 \ \ 2 \ 4.13-1.7x=4.028 \ 1.7x=4.13-4.028 \ 1.7x=0.102 \ x=0.120:1.7 \ x=0.06$

$3 \ 64:(2.4y+19.04)=3.2 \ 2.4y+19.04=64:3.2 \ 2.4y+19.04=20 \ 2.4y = 20-19.04 \ 2.4y = 0.96 \ y=0.96:2.4 \ y=0.4$
