x is​

If 3 ( 5x - 7) - 4 ( 8x - 13) = 2 ( 9x - 11) - 17, then the value of ( 7x - 5)/(11 x - 9) is

Given below is a finite sequence of numbers with an unknown x: 0,1, 1, 2, 3, 5, 8, 13, x, 34, The value of x is

Find the values of x and y in the following rectangle : We know that the opposite sides of a rectangle are equal therefore 3x + y = 7 …(1) x + 3y = 13 …(2) 9x + 3y = 21 [from (1)] {:(" x + 3y = 13"),( " "ul"- - -"),("On subtracting, 8x =8"):} x = 1 Now, from (1), 3 (1) + y = 7 implies y = 7 - 3 implies y = 4 Hence, the required values of x and y are 1 and 4 respectively.

If 2x -3 = 13 , then x = ______

If f(x)={:{(3x+5", for " 0 le x lt 3),(2x+8", for " 3 le x lt 5),(x+13", for " 5 le x le 10):} , then

If (13x^(2) + 30 x + 17)/(3x^(2) + 14 x + 8) gt 3 , then find the value of x, if x in R and x ne (-2)/(3), -4 .
