Answer 2

Solving the Equation 2a - (14 - 3a) = -10

To solve the equation 2a - (14 - 3a) = -10, we can follow these steps:

1. Distribute the Negative Sign: Distribute the negative sign inside the parentheses. 2. Combine Like Terms: Combine like terms on the left-hand side of the equation. 3. Isolate the Variable: Isolate the variable 'a' to solve for its value.

Let's go through these steps:

1. Distribute the Negative Sign: - The equation 2a - (14 - 3a) = -10 becomes 2a - 14 + 3a = -10 after distributing the negative sign inside the parentheses.

2. Combine Like Terms: - Combine the like terms on the left-hand side of the equation: 2a + 3a - 14 = -10. - This simplifies to 5a - 14 = -10.

3. Isolate the Variable: - To isolate the variable 'a', we can add 14 to both sides of the equation: 5a = -10 + 14. - This simplifies to 5a = 4. - Finally, divide both sides by 5 to solve for 'a': a = 4/5.

So, the solution to the equation 2a - (14 - 3a) = -10 is a = 4/5. This is the value of 'a' that satisfies the given equation.

Answer 3

2a - (14 - 3a) = -10

Сначала раскроем скобки:

2a - 14 + 3a = -10

Теперь объединим подобные члены:

5a - 14 = -10

Теперь добавим 14 к обеим сторонам уравнения, чтобы избавиться от отрицательного числа:

5a = 4
