If `[[2,3],[2x,5]]=[[2,3] ,[-3,5]]` then x=

If |[2x,x+3],[ 2(x+1),x+1]|=|[1, 5],[ 3 ,5]| , then write the value of xdot

Solve the equation: |[2,3],[4,5]|=|[x,3],[2x,5]|

If 2x+3y=5, 2y+z=3, and x+5y+z=3 , then x =

If |(3x,4),(5,x)|=|(4,-3),(5,-2)| , then x =

Solve the following: |[x+1, 3, 5], [2,x+2, 5], [2, 3,x+4]|=0

If (3^(2x-8))/(225)=(5^3)/(5^x) , then x= (a) 2 (b) 3 (c) 5 (d) 4

if f(x)=|[x-3,2x^2-18,3x^3-81],[x-5,2x^2-50,4x^3-500],[1,2,3]| then f(1)f(3)+f(3)f(5)+f(5)f(1) is equal to

If the mean of x+2,\ 2x+3,\ 3x+4,\ 4x+5 is x+2 , find x

Evaluate x and y if [(x,2),(-3,y)]=2[(x^(2),1),(-(3)/(2),3y-5)] .

(2x+5)/3=3x-10
