13(y-4)-3(y-9)-5(y+4)=0
You asked:
Solve the equation \(13 \left(y - 4\right) - 3 \left(y - 9\right) - 5 \left(y + 4\right) = 0\) for the variable \(y\).
MathBot Answer:
The solution is: \[y = 9\]
\[\begin{aligned}13 \left(y - 4\right) - 3 \left(y - 9\right) - 5 \left(y + 4\right) &= 0\\5 y - 45 &= 0\\5 y &= 45\\y &= 9\end{aligned}\]
