(3x-5y-11)*(3x-5y-11)+|9x+2y-16|=0怎么解?急急

4(x-y)-3(x-y)=9 5(x-y)+2(x-y)=11 3(x+y)-4(x-y)=11,2(x-y)+5(x+y)=27 （x+y-5)*（x+y-5)+（x-y+3)=0 x*x-y*y 已知:3x-5y=0,求x/y,x-y/y,x-y/x {x+y=5{3x-7y=11 3*X=Y X/2=Y/5+11 解方程组 {3(x+y)-4(x-y)=11 {2(x-y)+5(x+y)=27 解方程组 {3(x+y)-4(x-y)=11 {2(x-y)+5(x+y)=27全过程、快 解方程组：3(x+y)+2(x-y)=11,6(x+y)-5(x-y)=13. 接二元一次4(x+y)-3(x-y)=9;5(x-y)+2(x+y)=11 大括号x+y/2+x-y/3=11/6 4(x+y)-5(x-y)=7 快 1.x^4-4x^3+4x^2-92.y^5-11y^3+y 3x+2y=10.5 6x+5y=11y=x= 3x+5y=30 7x-8y=11 x是多少 y是多少 化简:5(x-y)+2(x+y)-3(x-y) (y-x)(x-y)^3(y-x)^5怎么算 已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y) (2x-3y)-(5x-y)
