(x-15)/(y+15)=3/4,(x+17)/(y-17)=11/4解方程(x-15)/(y+15)=3/4,(x+17)/(y-17)=11/4解方程(x-15)/(y+15)=3/4,(x+1
(x-15)/(y+15)=3/4,(x+17)/(y-17)=11/4解方程
(x-15)/(y+15)=3/4,(x+17)/(y-17)=11/4
解方程
(x-15)/(y+15)=3/4,(x+17)/(y-17)=11/4解方程
采用交叉积相等的原理
4（x-15）=3(y+15)
4(x+17)=11(y-17)
然后化简计算
4x-3y=105
4x-11y=-255
方程联立,得
x=60
y=45
x=1605/32;y=255/8
x=60
y=45
