The simplified expression is \(-3.7y\).
Solución
To simplify the expression \( 3.5y - 7.2y \), you can combine like terms by subtracting the coefficients of \( y \):
\[
3.5y - 7.2y = (3.5 - 7.2)y = -3.7y
\]
**Simplified expression:** \(-3.7y\)

To simplify \( 3.5y - 7.2y \), you combine the coefficients of \( y \). This means \( 3.5 - 7.2 = -3.7 \). So, the simplified form is \( -3.7y \). It's like gathering apples: if you start with 3.5 apples and take away 7.2, you end up with a negative number of apples! In algebra, combining like terms is a crucial skill. Remember, it works for any variables: just sum up the coefficients and keep the variable. If you've got \( 4x + 2x \), you happily report back with \( 6x \)!
