求y=4/3x-5/3,y=-14/3+5这两条直线与x轴围成的三角形的面积.我就是过程不太会.

已知:3x-5y=0,求x/y,x-y/y,x-y/x 已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(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 (-x+6):(x-y);(4x+y)=3;14:1,求x+y的值. (x-y)/(x+y)=3求( 3x-2y-1)/(x+y-5) x(x-3y)=4y(x-3y),求x:y 3y=18-5x 3x=4+5y 求x,y x+5y=4 3x-6y=5 求x ,y 若2x-3y=0,求5x+4y/3x-2y 5x-6y= -28 ,3x+4y=6求x与y 4x-3y=5 x^2+y^2=1 求x,y 求5x-2y=x-y=4x-3y-2的解 3y+12=x 4y+5=x ,求x,y 3x+4y-5=0 x^2+y^2=1求x.y 已知3X=4X,5Y=6Z求X+Y：Y+Z 5x+y=2,x-3y=4,求x和y, 5x+y=2 x-3y=4 求x和y
