(xiii) (xiv) (xv) If ( x v i ) (xvii) y=( x v i i i ) (xix) 35^(( x x )0( x x i ))( x x i i ) , (xxiii) (xxiv) what is the value of ( x x v ) (xxvi) x ? (xxvii) (xxviii)

Find the value of x , if y = 2 x − 5 and y = 7 .

Find the values of x and y in Fig. 6.37

Find the value of y in the equation 2x+y=7 , if x=2 .

In the equation 2x+y=7 , find the values of (i) y if x=2 and (ii) x if y=-1 .

If [x-y2x+y7]=[3187], then find the value of y.

if y=x^(n) then find the value of (d^(y))/(dx^(n))
