If twice the first number x is 5 less than 7 times
the second number y,
then which of the following equations is correct?
\(2x=7y-5\)
let translate the statement into equation
Twice the first number x” →2x
5 less than 7 times the second number y” → \(7y−5\)
According to the statement:
\(2x=7y−5\)
This is the correct equation.
