261*s 717
s - ----- = ---
500 200
$$- \frac{261 s}{500} + s = \frac{717}{200}$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Looking for similar summands in the left part:
Divide both parts of the equation by 239/500
We get the answer: s = 15/2
s-(261/500)*s = (717/200)
Expand brackets in the left part
s-261/500s = (717/200)
Expand brackets in the right part
s-261/500s = 717/200
Looking for similar summands in the left part:
239*s/500 = 717/200
Divide both parts of the equation by 239/500
s = 717/200 / (239/500)
We get the answer: s = 15/2
