一道简单的二元一次方程S/(V+1)=4.5S/(V-1)=16/3一道简单的二元一次方程S/(V+1)=4.5S/(V-1)=16/3一道简单的二元一次方程S/(V+1)=4.5S/(V-1)=16

一道简单的二元一次方程S/(V+1)=4.5S/(V-1)=16/3
一道简单的二元一次方程
S/(V+1)=4.5
S/(V-1)=16/3

一道简单的二元一次方程S/(V+1)=4.5S/(V-1)=16/3
S/(V+1)=4.5
S=4.5(V+1)
代入S/(V-1)=16/3
4.5(V+1)=16(V-1)/3
13.5V+13.5=16V-16
2.5V=29.5
V=11.8
S=4.5(V+1)=57.6
