0s+1=7+45s
Multiply 0 and 5 to get 0.
0+1=7+45s
Anything times zero gives zero.
1=7+45s
Add 0 and 1 to get 1.
7+45s=1
Swap sides so that all variable terms are on the left hand side.
45s=1-7
Subtract 7 from both sides.
45s=-6
Subtract 7 from 1 to get -6.
s=\frac{-6}{45}
Divide both sides by 45.
s=-\frac{2}{15}
Reduce the fraction \frac{-6}{45} to lowest terms by extracting and canceling out 3.
