If (6)/(2x -3) +6a=(10)/(2x -3) + 4b and 3a -2b =2, what is the value of x ?

If the points A(x, 2), B(-3, -4) and C(7, -5) are collinear then the value of x is ?

If the maximum and minimum values of y=(x^2-3x+c)/(x^2+3x+c) are 7 and 1/7 respectively then the value of c is equal to (A) 3 (B) 4 (C) 5 (D) 6

if a/3 =b/7 =(7a-2b)/x , then find the value of x.

If A(x,2),B(-3,-4) and C(7,-5) are collinear,then the value of x is

If [2x+y,4x,5x-7 4x]=[7 7y-13 y x+6] , then the value of x+y is x=3 , y=1 (b) x=2 , y=3 (c) x=2 , y=4 (d) x=3 , y=3

If the maximum and minimum values of y=(x^(2)-3x+c)/(x^(2)+3x+c) are 7 and (1)/(7) respectively then the value of c is equal to (A)3(B)4(C)5 (D) 6

2x(3x+5)+3(3x+5)=ax^(2)+bx+c In the equation above, a, b, and c are constants. If the equation is true for all values of x, what is the value of b ?
