3x + 4y = 10, 2x-2y = 2

If x - y = 10 and x = 2y, then

If (x+y) = 12 and (x-y) = 4 then (2x - 4y) = ?

(x + y) ^ (10) = x ^ (8) y ^ (2)

( 10 )/( x+ y) + (2 ) /(x - y ) = 4 , ( 15)/( x + y ) - (9) /( x - y) = - 2 .

Find the values of (x-y) , if (i) 3x + 4y = 11 , 4x + 3y = 10 (ii) 3x + 2y = 8 , 2x + 3y = 7

2-2 (3x-y) = 10 (4-y) -5x = 4 (yx)

I. x^(2) +20x + 4 = 50 -25x II. y^(2) - 10y - 24 = 0
