The following equations are solved by the method of addition, subtraction and elimination
⑴、x+1/3=y+2/4 （1）
x-3/4-(y-3)/3=1/12 （2）
The results are as follows
From (1) * 12, it is concluded that:
12X-12Y==2 (3)
From (2) * 12, it is concluded that:
12X-4Y==22 (4)
(3) (4)
-8Y==-20
Y==5/2
X==8/3
⑵、0.2x+0.5y=0.2 （1）
0.4x+0.1y=0.4 （2）
The results are as follows
From (1) - (2) * 5, it is obtained that:
-1.8X==-1.8
X==1
From (1) * 2 - (1), it is obtained that:
0.9Y==0
Y==0
