`x+((5x)/4)+((6x)/5)=69`

Solve x: (x)/(4)=6x-(5)/(4)

If (5x)/2-1/4(6x-5/3) = 7/6 , then the value of x is _________

If A=[{:(2,3,10),(4,-6,5),(6,9,-20):}] , find A^(-1) . Using A^(-1) , solve the system of equations : {:((2)/(x)+(3)/(y)+(10)/(z)=2),((4)/(x)-(6)/(y)+(5)/(z)=5),((6)/(x)+(9)/(y)-(20)/(z)=-4):}

Solve the following: (sqrt(x^(2)-5x+6)+sqrt(x^(2)-5x+4))^((x)/(2))+(sqrt(x^(2)-5x+6)-sqrt(x^(2)-5x+4))^(x/2)=2^((x+4)/(4))

lim_(x to 0) ((2x-3)(3x-4))/((4x-5)(5x -6))

lim_(x to 0) ((2x-3)(3x-4))/((4x-5)(5x -6))

Statemenr I: If (3x+2)/(5)=(4x-7)/(6) thenx =23(1)/(2) Statement II: If 5(2x-9)/(3)8=2x then x=69/5

lim_(xrarroo)((2x-3)(4x-5))/((5x-6)(6x-7)) is equal to

Find the derivative of i) 2x-3/4 ii) (5x^(3)+3x-1)(x-1) iii) x^(-3)(5+3x) iv) x^(5)(3-6x^(-9)) v) x^(-4)(3-4x^(-5))
