Question

Найди корень уравнения 1)16(4х-3.4)=6.08 2)(х-1.25)*4.5=27 3)(х+19.64)*0.18=144 4)17(1.6-5х)=2.38

Answer 1

1)0,945
2)7,25
3)780,36
4)0,292

Answer 2

1)
4х-3.4=6.08÷16
4х-3.4=0.38
4х=0.38+3.4
4х=3.78
х=3.78÷4
х=0.945

2)
х-1.25=27÷4.5
х-1.25=6
х=6+1.25
х=7.25

3)
х+19.64=144÷0.18
х+19.64=800
х=800-19.64
х=780.36

4)
1.6-5х=2.38÷17
1.6-5х=0.14
5х=1.6-0.14
5х=1.46
х=1.46÷5
х=0.292
