4-s over 7-s = 3 over s-7...

LCD is s-7

then

(s-7)(4-s over 7-s) = (s-7) (3 over s-7)?

am I on the right track???

(4-s)/(7-s) = 3/(s-7)

notice one denominator is the negative of the other, so

(s-4)/(s-7) = 3/(s-7)

then

s - 4 = 3

s = 7

BUT;, s = 7 makes our denominators zero and our fractions would be undefined, so ...

no solution.
