−4y−4+(−3) PLZ SOMEONE HELP
The expression −4y−4+(−3) simplifies to −4y −7 by combining the numeric constants according to the rules of addition for negative numbers.
To combine the like terms in the expression −4y−4+(−3), we look for terms that have the same variable raised to the same power. Here, there are no like terms withy, so we just combine the constant numbers.
Following the rules for addition and subtraction of numbers:
1. When two negative numbers add, the answer has a −ve sign. For example, −4 + (−3) = −7.
2. In subtraction, change the sign of the subtracted number and then follow the addition rules.
Applying these rules to the given expression:
−4y−4+(−3)Therefore, the equivalent expression after combining like terms is −4y −7.
