Question 25677
My first observation is that the two y's cancel out so the input value of y is irrelevant; so maybe the question is supposed to be

5x+y/{1.3y+6}=
x=.24  y=.5

Substitute values of x=0.24 and y=0.5 into equation:

Ans = 5 * 0.24 + 0.5/{1.3 * 0.5 + 6}

Ans = 1.2      + 0.5/{0.65 + 6}

Ans = 1.2      + 0.5/6.65

Ans = 1.2      + 0.075

Ans = 1.275

I hope that is right.  It is the first time I have answered one of these questions.
