We need to find the solution to the equation


3y^(2)-7y=0

Step 1

Rewrite the expression on the left side, grouping the common factor, as follows:


\begin{gathered} 3y\cdot y-7y=0 \\ \\ y(3y-7)=0 \end{gathered}

Step 2

Notice that the above equation holds when one of the factors is zero:


\begin{gathered} y=0 \\ or \\ 3y-7=0 \\ 3y=7 \\ y=(7)/(3) \end{gathered}

Answer

Since both 0 and 7/3 are already reduced to the lowest terms, the answer is


\begin{gathered} y=0 \\ or \\ y=(7)/(3) \end{gathered}
