(x+y-8)/(2)=x+(2y-14)/(2)=(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.

Solve the following equations by Cramer’s method. (x + y - 8)/(2) = (x + 2y - 14)/(3) = (3x - y)/(4)

(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) )
