Question

1) 4(x - 1) + 3(x + 2) = 7x + 2

Answer 1

Ответ:2=2

Объяснение:

Розподіліть значення в дужках: 4x - 4 + 3x + 6 = 7x + 2

Об’єднайте однакові члени з обох сторін рівняння: 7x + 2 = 7x + 2

Відніміть 7x з обох частин рівняння, щоб виділити постійні члени: 7x - 7x + 2 = 2

Спростіть рівняння: 2 = 2

Answer 2

To solve the equation 4(x - 1) + 3(x + 2) = 7x + 2, you'll need to simplify and solve for the value of x. Here's how you can do it step by step:

1. Distribute the constants inside the parentheses: 4(x) - 4(1) + 3(x) + 3(2) = 7x + 2

2. Now, simplify the equation further by multiplying: 4x - 4 + 3x + 6 = 7x + 2

3. Combine like terms on both sides of the equation: (4x + 3x) - 4 + 6 = 7x + 2

4. Simplify the left side by combining the x terms and the constants: 7x + 2 = 7x + 2

At this point, you can see that both sides of the equation are the same:

7x + 2 = 7x + 2

This equation doesn't have a unique solution for x because the variable x cancels out on both sides. This means that the equation is true for any value of x. In other words, it is an identity, and x can take any real value. The solution is that x can be any real number.
