Question

how to solve for s: ((0.154*s)-161700)/1800000=((0.154*s)-69300)/3000000

Answer 1

Find the LCD.
The LCD is 9,000,000
\[\frac{5(0.154s-161700)}{9000000}=\frac{3(0.154s-69300)}{9000000}\]
Thus,
\[5(.0154s-161700)=3(0.154s-69300)\]
Distribute the 5 on the left side of the equation and the 3 on the right side.
\[.77s-808500=.462s-207900\]
Isolate s and solve:
\[.308s=600600\]
\[\frac{.308s}{.308}=\frac{600600}{.308}\]
\[s=1950000\]
