若10.5x-10=36-3y=14+4.5x,求x和y的值

若10.5x -10 = 36-3y=14+A,x=?y=? 若(-x+6):(x-y):(4x+y)=3:14:1,求x+y 若(-x+6):(x-y):(4x+y)=3:14:1,求x+y 若10.5x-10=36-3y=14+4.5x,求x和y的值 若10.5X-10=36-3y=14+4.5X,求X和Y的值 3(x+y)+2(x-y)=36 4(x+y)-5(x-y)=2 4x-2*(10-x)-10=5y-3*(10-y)x+y=14 3(x+y)+4(x-y)=36 2(x+y)=-10的解! 若x^2-4x+y^2-10y+29=0,求x^2y^2+2x^3y^2+x^4y^2的值 例X=1 y=21.X+Y=5 X-Y=15 2.2X+3Y=4 5X+6Y=7 3.X+3Y=5 3X+Y=-1 4.2X+Y=3 3X+5Y=11 5.4X+3Y=6 2X+Y=4 6.X+Y=180 X=3Y-10 7.3X-2Y=3 2X-Y=7 8.5X+3Y=7Y X+Y=45 9.3X+4Y=126X+8Y=24 X:6Y=1:4 10.X+Y=138 X-45=Y+53 11.X+Y=60 14Y=20X 12.2X+3Y=15.5 5X+6Y=35 13.X+Y=170 3 (4x-2y-z)-{5x[8y-2y-(x+y)]-x+(3y-10z)]=? kuaihuajian 若10.5x-10=36-3y=14+A,则x=（ ）,y=( ) 若10.5x-10=36-3y=14+A,求x和y的值 (-x+6):(x-y);(4x+y)=3;14:1,求x+y的值. 比例线段若x+y/x-y=4/3,则x/y=x+y/x-y=4/3,则x/y=要快~~ 3x+x+4y+(90+10)x=3y-(2x+y)+510y=34x 若(X×X+Y×Y)(X×X+Y×Y-5)=36,则X×X+Y×Y＝ 若x+y=4,则多项式1/2(x+y)+4(x-y)-3（x-y）-3/2(x+y)-x+y值是（）
