s=\frac{4t\left(s+3\right)}{2\left(t+1\right)}
Factor the expressions that are not already factored in \frac{4t\left(s+3\right)}{2t+2}.
s=\frac{2t\left(s+3\right)}{t+1}
Cancel out 2 in both numerator and denominator.
s=\frac{2ts+6t}{t+1}
Use the distributive property to multiply 2t by s+3.
s-\frac{2ts+6t}{t+1}=0
Subtract \frac{2ts+6t}{t+1} from both sides.
\frac{s\left(t+1\right)}{t+1}-\frac{2ts+6t}{t+1}=0
To add or subtract expressions, expand them to make their denominators the same. Multiply s times \frac{t+1}{t+1}.
\frac{s\left(t+1\right)-\left(2ts+6t\right)}{t+1}=0
Since \frac{s\left(t+1\right)}{t+1} and \frac{2ts+6t}{t+1} have the same denominator, subtract them by subtracting their numerators.
\frac{st+s-2ts-6t}{t+1}=0
Do the multiplications in s\left(t+1\right)-\left(2ts+6t\right).
\frac{-st+s-6t}{t+1}=0
Combine like terms in st+s-2ts-6t.
-st+s-6t=0
Multiply both sides of the equation by t+1.
-st+s=6t
Add 6t to both sides. Anything plus zero gives itself.
\left(-t+1\right)s=6t
Combine all terms containing s.
\left(1-t\right)s=6t
The equation is in standard form.
\frac{\left(1-t\right)s}{1-t}=\frac{6t}{1-t}
Divide both sides by -t+1.
s=\frac{6t}{1-t}
Dividing by -t+1 undoes the multiplication by -t+1.
s\times 2\left(t+1\right)=4t\left(s+3\right)
Variable t cannot be equal to -1 since division by zero is not defined. Multiply both sides of the equation by 2\left(t+1\right).
2st+s\times 2=4t\left(s+3\right)
Use the distributive property to multiply s\times 2 by t+1.
2st+s\times 2=4ts+12t
Use the distributive property to multiply 4t by s+3.
2st+s\times 2-4ts=12t
Subtract 4ts from both sides.
-2st+s\times 2=12t
Combine 2st and -4ts to get -2st.
-2st+s\times 2-12t=0
Subtract 12t from both sides.
-2st-12t=-s\times 2
Subtract s\times 2 from both sides. Anything subtracted from zero gives its negation.
-2st-12t=-2s
Multiply -1 and 2 to get -2.
\left(-2s-12\right)t=-2s
Combine all terms containing t.
\frac{\left(-2s-12\right)t}{-2s-12}=-\frac{2s}{-2s-12}
Divide both sides by -2s-12.
t=-\frac{2s}{-2s-12}
Dividing by -2s-12 undoes the multiplication by -2s-12.
t=\frac{s}{s+6}
Divide -2s by -2s-12.
t=\frac{s}{s+6}\text{, }t\neq -1
Variable t cannot be equal to -1.
