If `2x+3y=0` and `4x-3y=0`then `(x+y)` equals `

The lines x=3,y=4and 4x-3y+a=0 are concurrent for a equal to

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

If x + y -7 =0 and 3x + y -13 = 0 . then what is 4x^(2) + y^(2) + 4xy equal to?

If x+y-7=0 and 3x+y-13=0 , then what is 4x^(2)+y^(2)+4xy equal to ?

If x-4y= 0 and x+2y= 24 , then what is the value of (2x+3y)//(2x-3y) ?

2x+y=0 is the equation of a diameter of the circle which touches the lines 4x-3y+10=0 and 4x-3y-30=0 The centre and radius of the circle are

The equaiton of the lines representing the sides of a triangle are 3x - 4y =0 , x+y=0 and 2x - 3y = 7 . The line 3x + 2y = 0 always passes through the

The equations of sides of a triangle are x+3y=0 , 4x-3y=5 and 3x-y=0. Then the line 6x-7y=0 passes through the __________ of the triangle.

Find the equation of the circle which touches the lines 4x-3y+10=0 and 4x-3y-30=0 and whose centre lies on the line 2x+y=0 .
