2 lần số lớn :
141,2 - ( 34,4 x 3 ) = 38
Số lớn :
38 : 2 = 19
Số bé :
34,4 - 19 = 15,4
đ/s : 19 và 15,4
Gọi 2 số là a và b
ta có a+b = 34,4
ax5+bx3=141,2
ax2+(a+b)x3+141,2
a x 2 +34,4 x3 =141,2
ax2+103,2=141,2
ax2=141,2=103,2
ax2 =38
a=38:2
a=19
vậy b=34,4-19
vậy b = 15,4

2 lần số lớn :
141,2 - ( 34,4 x 3 ) = 38
Số lớn :
38 : 2 = 19
Số bé :
34,4 - 19 = 15,4
đ/s : 19 và 15,4
Gọi hai số là A,B ta có
A+B=34,4
Ax5+Bx3=141,2
Ax2+(A+B)x3=141,2
Ax2+34,4x3=141,2
Ax2+103,2=141,2
Ax2=141,2-103,2
Ax2=38
A=38:2
A=19
Vậy B=34,4-19=15,4
