Question

647-(183+75 246+4х70-158

Answer 1

Ответ:

Вопрос немного некорректный поэтому я сделала два варианта решений учитывая каким могло бы быть задание

647-(183+75)=647-258=389

246+4x+70-158=158+4x

647-(183+75)=246+4x+70-158

389=158+4x

4x=158-389

4x=-231

x=-57,75

Answer 2

To simplify the expression 647 - (183 + 75) + (246 + 4 * 70) - 158, follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right):

1. First, calculate what's inside the parentheses/brackets: 183 + 75 = 258 4 * 70 = 280

2. Now, rewrite the expression with the simplified values: 647 - 258 + 246 + 280 - 158

3. Next, perform addition and subtraction from left to right: 647 - 258 = 389 389 + 246 = 635 635 + 280 = 915 915 - 158 = 757

So, the simplified result of the expression is 757.
