若|5x-2x-3|+(x+6y-11)^2=0成立,求x.y的值

若2x-3y+4=0则x（x*x-1)+x(5-x*x)-6y+7 若|5x-2y-3|+(x+6y-11)X(x+6y-11)=0成立,求x,y的值 若|5x-2y-3|+(x+6y-11)X(x+6y-11)=0成立,求x,y的值, [2(x-y)^5-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2[2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2 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 2(2x+3y)(3x+2y)-(6x-y)(2x-5y) 若(x-y)/(x+y)=3 则(x+2y)/(6x-7y)等于 x+y/2+x-y/6=5 2(x+y)-3(x-y)=-2 因式分解x次方-y次方+5x-y+6【x-y+2】【x+y+3】 6(x-y)-2(x+y)=14 3(x-y)+(x+y)=5 若|5x-2x-3|+(x+6y-11)^2=0成立,求x.y的值 因式分解3x^2(x-y)+6x(y-x) 解方程组：3(x+y)+2(x-y)=11,6(x+y)-5(x-y)=13. 大括号x+y/2+x-y/3=11/6 4(x+y)-5(x-y)=7 快 若5x+3y=3x+4y=x+2y+6,则x+y=___ 3x+2y=10.5 6x+5y=11y=x= 1.(x^3-x^2-4x+1)/(x^2-3x+2)-(x^3-2x^2-9x+21)/（x^2-5x+6）+（x^2-3x+8）/（x^2-4x+3）2.{(x^2)/（x-y)}*{y/(x+y)}-{(x^4y)/(x^4-y^4)}÷{（x^2/x^2+y^2）^2}
