" 13."3x+2(x+2)=20-(2x-5)

Solve 3x + 2(x + 2) = 20 - (2x - 5)

Solve : 3x + 2 (x+2) = 20 - (2x -5)

If (9x-13)/(x^(2)-2x-15)=(A)/(x+3)+(B)/(x-5) , then A+B is ________.

5^(13-2x)+2^(x-2)= 2^(x+2)+5^(11-2x)

Factorise (i) x ^(2) - 2x ^(2) - x +2 (ii) x ^(3) - 3x ^(2) - 9x -5 (iii) x ^(3) + 13 x ^(2) + 32 x + 20 (iv) y ^(3) + y ^(2) -y -1

Solve for x and y : ( 3x )/( 2) - ( 5y )/( 3) = - 2, ( x)/(3) + ( y)/(2) = (13)/(6)

Solve: (6x^2+\ 13 x-4)/(2x+5)=(12 x^2+5x-2)/(4x+3)
