0.4x-1.5y=6.5,0.3x+0.2y=0.9

Solve the following system of by the method of eliminations: 0.4x-15y=6.5 ,0.3x+0.2y=0.9

Solve for x and y : 0.4 x - 1.5 y = 6.5 , 0.3 x + 0.2 y = 0.9 .

[0.2x+0.3y=1.3],[0.4x+0.5y=2.3]

0.2x + 0.3y = 1.3,0.4x + 0.5y = 2.3

Classify the following pairs of lines as coincident,parallel or intersecting: x+2y-3=0 and -3x-6y+9=0x+2y+1=0 and 2x-4y+3=03x-2y+5=0 and 2x+y-9=0

The figure formed by the lines 2x-5y+4=0, 5x+2y+7=0, 2x-5y+3=0, 5x+2y-6=0 is

Find the following products: (i) (0.9x+0.7y)(0.81x^(2)-0.63xy+0.49y^(2)) (ii) ((2x)/(5)-(3y)/(7))((9y^(2))/(49)+(4x^(2))/(25)+(6xy)/(35))

5x+7y+2=0 4x+6y+3=0

Solve the following system of equations by matrix method : 5x+7y+2=0 4x+6y+3=0 5x+2y=3 3x+2y=5 3x+4y-5=0 x-y+3=0 3x+y=19 3x-y=23 3x+7y=4 x+2y=-1 3x+y=7 5x+3y=12
