" 20.If "(4x+5):(3x+11)=13:17," find the value of "x" ."

If (4x+5):(3x+11)=13 : 17 , find the value of xdot

If 1/3 x + 5 = 17 , find the value of x.

If x=-3 find the value of 4x^2-5x+3

If f(x+2)=3x+11 and g(f(x))=2x, find the value of g(5).

(i) x+2y=-7 and 3x-2y=-1, then find the value of x. (ii) If x+y=8 and 4y-x=2, then find the value of y. (iii) If 3x+5y=9 and 5x+3y=7, then find the value of x+y. (iv) If 3x-y=11 and x-3y=17, then find the value of x-y.
