To simplify the expression 4y + 7y – 9y, we can combine like terms.
When we add or subtract variables with the same base (in this case, ‘y’), we can combine their coefficients.
The coefficients of the ‘y’ terms are 4, 7, and -9. Adding these coefficients together, we get:
4y + 7y – 9y = (4 + 7 – 9)y
Simplifying further:
= 2y
Therefore, the simplified form of the expression 4y + 7y – 9y is 2y.
