Решите уравнения: 1) х+2,7=3 ; 2) х-0,6=1,4 ; 3) 3/4+х=1 ; 4)х-1 1/5=4/5 $5)2х-5=х-1 ; 6) 2,7х+1,3=х+3

1) x+2.7 = 3
x = 3-2.7
x = 0.3

2) x-0.6 = 1.4
x = 1.4+0.6
x = 2

3)3/4 + x = 1
x = 1-3/4
x = 4/4-3/4
x = 1/4

4)x-1 1/5 = 4/5
x = 4/5+1 1/5
x = 2

5) 2x-5 = x-1
2x-x = 5-1
x = 4

6) 2.7x+1.3 = x+3
2.7x-x = 3-1.3
1.7x = 1.7
x = 1.7/1.7
x = 1
