(там где есть а все они сокращаются и все остальное сложение и вычитание)-9а+5а+4а=0

Answer 2

Solving the Equation -9(a + 7) + 117.3 + 0.5(10a - 3) - 2.5 + 4a

To solve the given equation, we'll follow the standard order of operations: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

1. Simplify within Parentheses: - First, we'll simplify the expressions within the parentheses.

- The expression -9(a + 7) can be simplified to -9a - 63. - The expression 0.5(10a - 3) can be simplified to 5a - 1.5.

- The equation now becomes: -9a - 63 + 117.3 + 5a - 1.5 - 2.5 + 4a.

2. Combine Like Terms: - Next, we'll combine the like terms in the equation.

- Combining the terms with 'a', the equation becomes: -9a + 5a + 4a. - Combining the constant terms, the equation becomes: -63 + 117.3 - 1.5 - 2.5.

- The equation now becomes: -9a + 5a + 4a - 63 + 117.3 - 1.5 - 2.5.

3. Solve for 'a': - Now, we'll combine the like terms and solve for 'a'.

- Combining the 'a' terms, the equation becomes: 0a. - Combining the constant terms, the equation becomes: 50.8.

- Therefore, the solution to the equation -9(a + 7) + 117.3 + 0.5(10a - 3) - 2.5 + 4a is a = 50.8.

This is the solution to the given equation.
