Answer 1

a-b = 33
a*0.3 = 2/3*b
a = 33+b
(33+b)*0.3 = 2/3*b
6.6+b*0.3 = 2/3*b
2/3*b - b*0.3 = 6.6
2b - 0.9b = 19.8
1.1b = 19.8
b=19.8/1.1 
b = 18
Находим a;
a-18=33
a=33+18
a=51

Answer 2

a-b=33;
a>b;
0.3a=2/3b;⇒b=(3/10)·a:(2/3)=(3/10)·a·3/2=(9/20)·a;
a-(9/20)a=33;⇒11/20·a=33;⇒
a=33:(11/20)=60;
b=9/20·60=27;
a=60;b=27;
