Write an equation equivalent to 2x+3y=5

To find an equation equivalent to \(2x + 3y = 5\) by multiplying the entire equation by 4, you will distribute the 4 to each term in the equation:

\[
4(2x) + 4(3y) = 4(5)
\]

Calculating each term gives:

\[
8x + 12y = 20
\]

Therefore, the equation \(2x + 3y = 5\) is equivalent to:

\[
8x + 12y = 20
\]
