4x + y = -6 x+ 3y = 4 multiply 2nd eqn by -4 and add both, to get => 4x+y -4x - 12y = -6 - 16 => - 11 y = - 22 => y = 2, put y =2 in eqn (2), to get => x + 3(2) = 4 => x = 4 - 6 = -2 Answer x=-2, y=2

3x + 4y = 8.10 --------------(1) x +3y = 4.20 ---------------(2) multiply 2nd eqn by -3 and add , to get (3x + 4y ) - (3x - 9y) = (8.1) - 12.6 => - 5y = - 4.5 => y = 4.5 / 5 = 0.9 put this in Eqn (2), to get => x + 3(0.9) = 4.2 => x = 4.2 - 2.7 = 1.5 so x = 1.5 ; y = 0.9 Answer Is it correct?

yes people change by learning and experiece- this is a scientific way. man has brain and can decide which path or action are good and what attitudes/behavior patterns are be made part of our life.

Greek civilization was very much advanced in Arts, Philosophy, Maths, Architecture etc. In fact the composition of the drawings is the best. But I have a doubt. The egyptians believed that the kings etc would get another life after death, so they were buried in the chambers called pyramids, and...

u had spotting,so do take the test...it might b positive
