`2x-y=4` and `3x-2y=5`

If 2x+3y=5 and 3x+2y=10 then x-y= (a) 3 (b) 4 (c) 5 (d) 6

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

Solve the following pair ofequations by substitution method.(3)/(2)x-y=(1)/(4);x+(1)/(2)y=1 and 3x+y=4,2(y-5)=-5x

Solve:- 2x+3y=4 3x-y=-5 .

Subtract the sum of - 3x^3y^2 + 2x^2 y^3 and - 3x^2y^3 - 5y^4 " from " x^4 + x^3y^2 + x^2y^3 + y^4

Solve 3x - 4y = 20 and x + 2y = 5.

(i) 2x+3y=4;3x-y=-5

Show that the following system of equations is inconsistent: 2x+y=3,\ \ \ 4x+2y=5
