Answer 2

I can help you with math problems. To simplify the expression, you need to apply the rules of addition and subtraction of signed numbers. Here are the steps:

-а + 45 – 65 + (-b) + 65 - 33 + b - (-а)​

= -а + (-b) + b + (-а) + 45 + 65 - 65 - 33

= -2а + 0 + 12

= -2а + 12

The simplified expression is $$-2а + 12$$.Ответь+подробно.++10.Спростіть+вираз:+-а+++45+–+65+++(-b)+++65+-+33+++b+-+(-а).​+
