यदि `2x-3y=7` तथा `(a+b)x-(a+b-3)y=4a+b` के अपरिमित हल होंगे यदि -

2x + 3y = 7& (a-b)x+ (a + b) y = 3a + b-2

2x + 3y =7 , (a + b ) x + ( 2a - b ) y = 21 .

If a^3-b^3=1603 and (a-b)=7, then (a+b)^2 -ab is equal to: यदि a^3-b^3=1603 तथा (a-b)=7, तो (a+b)^2 -ab का मान किसके बराबर होगा ?

If 2x-3y=7 and (a+b)x-(a+b-3)y=4a+b represent coqucident lines,then a and b satisfy the equation?

If 2x-3y=7" and "(a+b)x-(a+b-3)y=4a+b represent coincident lines, then a and b satisfy the equation :

2x + 3y = 7 , (a+b + 1 )x + (a + 2b + 2) y = 4 (a + b ) + 1

If a^3-b^3=899 and a-b=31, then (a-b)^2 +3ab is equal to: यदि a^3-b^3=899 तथा a-b=31, तो (a-b)^2 +3ab का मान क्या होगा ?

If a^3+b^3=432 and a+b=12, then (a+b)^2 -3ab is equal to: यदि a^3+b^3=432 तथा a+b=12, तो (a+b)^2 -3ab का मान क्या होगा ?

If a^3+b^3=110 and a+b=5, then (a+b)^2 -3ab is equal to: यदि a^3+b^3=110 तथा a+b=5, तो (a+b)^2 -3ab का मान क्या होगा ?
