If \dfrac{1}{2}+\dfrac25s=s-\dfrac34 2 1 + 5 2 s=s− 4 3 start fraction, 1, divided by, 2, end fraction, plus, start fraction, 2, divided by, 5, end fraction, s, equals, s, minus, start fraction, 3, divided by, 4, end fraction , what is the value of sss?

We write the mathematical expression correctly:   1/2 + (2/5) s = s - 3/4  we group similar terms:   s (1- (2/5)) = 1/2 - 3/4  we rewrite:   s (5 / 5- (2/5)) = 2/4 - 3/4  s (3/5) = -1/4  s = (5/3) * (- 1/4)  s = -5 / 12  answer:   the value of s is:   s = -5 / 12
