Помогите решить..... х-3,2=2,7/15 4,7/12-y=2,5 0,6х=9/20 x:5/9=3,6 5/6y=0,5

X-3.2=2.7/15
x=2.7/15+3.2/1
x=(2.7+48)/15
x=50.7/15
x=3.38
_________
4.7/12-y=2.5
y=(4.7-30(/12
y=-25.3/12
y=-2*13/120
_________
0.6x=9/20
x=(9/20)/(0.6/1)
x=9/12
x=0.75
_________
x:5/9=3.6
x=(5*3.6)/9
x=18/9
x=2
_________
5/6y=0,5
y=(0.5*6)/5
y=3.5
y=0.6
