[24.2x+3y=7],[(a+b+1)x+(a+2b+2)y=4(a+b)+1]

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

2x+3y=7(a+b)x+y(2a-b)=3(a+b+1) find the value of a+b

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 :

Factorize each of the following expressions: x a^2+x b^2-y a^2-y b^2 (2) x^2+x y a+x z+y z (3) 2a x+b x+2a y+b y (4) a b-b y-a y+y^2

Factorize each of the following algebraic expressions: x^(3)(a-2b)+x^(2)(a-2b)2x-3y)(a+b)+(3x-2y)(a+b)4(x+y)(3a-b)+6(x+y)(2b-3a)

Solve the following system of equations in xa n dy a x+b y=1 b x+a y=((a+b)^2)/(a^2+b^2)-1or ,b x+a y=(2a b)/(a^2+b^2)

If a, b are noncollinear vectors and A = (x + 4y) a + (2x + y + 1)b, B = (y - 2x +2) a + (2x - 3y - 1) b and 3A = 2B, then (x, y) =

Find x,y, a and b if [(2x+3y , a+b, 8),(1, 4x + y , 3a-4b)] = [(7,1,8),(1,9,10)] .
