若实数x,y满足(x-y-5)²+│2x+3y+20│=20,求3x+2y+1的值.同上:若实数x,y满足(x-y-5)²+│2x+3y+20│=20,求3x+2y+1的值.若实数

若实数x,y满足(x-y-5)²+│2x+3y+20│=20,求3x+2y+1的值.同上:若实数x,y满足(x-y-5)²+│2x+3y+20│=20,求3x+2y+1的值.
若实数x,y满足(x-y-5)²+│2x+3y+20│=20,求3x+2y+1的值.
同上:若实数x,y满足(x-y-5)²+│2x+3y+20│=20,求3x+2y+1的值.

若实数x,y满足(x-y-5)²+│2x+3y+20│=20,求3x+2y+1的值.同上:若实数x,y满足(x-y-5)²+│2x+3y+20│=20,求3x+2y+1的值.
此题等式右边应该是0吧,不然此题就有无数组解.如果是0的话,由(x-y-5)²≥0,│2x+3y+20│≥0知,要使等式成立必有(x-y-5)²=0且│2x+3y+20│=0,那么3x+2y+1=-14

若实数X,Y满足x²+y²-4x-2y+5=0求√x+y/√8y-2x 若实数x,y满足x²+y²-2x+4y=0,求x-y的最大值若实数X,Y满足方程5X²-12XY+10Y²-6X-14Y+13=0,则X=?Y=? 若实数a,b,x,y满足ax+by=3和ay+bx=5,求(a²+b²)(x²+y²) 若实数XY满足X+Y²=1,则2X²;+8Y²的最小值是有道数学题不会算了……若实数x,y满足x ²+4y ²=4x,求x ²+y ²的取值范围. 若实数x,y满足x²+4y²=4x,求S=x²+y²的取值范围若实数x,y满足5x-12y+2=0,则(x-13)²+(y+2)²的最小值若x,y为实数,且满足y=√﹙xy-6﹚+√(6-xy)+5-x,则x²+y²=? 若实数x,y满足xy>0,且x²y=2,则xy+x²的最小值是? 若实数x,y满足2x²+3y²=1,S=3x²-2y²,则S的取值范围是多少设x=a²b²+5,y=2ab-a²-4a,若x>y,则实数a,b需满足什么条件? 已知实数满足x²+4y²=4x,求x²+y²的最值求详细过程。。。若实数x,y满足x²+y²-2x+4y=0,则x-2y的最大值? 已知实数x、y满足5x²-3xy+1/2y²-2x+1/2y+1/4=0 求x、y的值已知实数x、y满足5x²-3xy+1/2y²-2x+1/2y+1/4=0 求x、y的值若实数x,y满足y 若实数x,y满足不等式y
