((a))/(2)=(x+2y-14)/(3)=(3x+y-12)/(11)

If (x+y-8)/2 = (x+2y-14)/3 = (3x+y-12)/11 , then find the values of x and y, respectively.

(x + y - 8) /( 2 ) = ( x + 2y - 14 ) /( 3) = ( 3x + y - 12)/( 11)

Let (x,y,z) be an arbitrary point lying on a plane P which passes through the points (42,0,0), (0,42,0) and (0,0,42), then the value of the expression 3+(x-11)/((y-19)^(2)(z-12)^(2))+(y-19)/((x-11)^(2)(z-12)^(2))+(z-12)/((x-11)^(2)(y-19)^(2))-(x+y+z)/(14(x-11)(y-19)(z-12)) is equal to :

x,y,z be a point on plane passing through (42,0,0),(0,42,0),(0,0,42) then value of (x-11)/((y-19)^2* (z-12)^2 )+(y-19)/((x-11)^2* (z-12)^2) +(z-12)/((x-11)^2* (y-19)^2)+3 -(x+y+z)/(14(x-11)* (z-12)*(y-19) )

{:(2x - 3y = - 13),(3x - 2y = - 12):}

Find x and y if :- ((x+2y, 14),(-3, y-2))=((4, 14),(-3, 7+3x)) .

Factorise (2x+3y)^(2)+14(2x+3y)(3x-y)-32(3x-y)^(2) .
