Answer 3

I can help you solve the equation. Here are the steps:

- First, we need to expand the brackets on the right side of the equation. To do this, we multiply 2 by each term inside the brackets. We get:

$$7x - 4 = 2x + 6$$

- Next, we need to collect the terms with x on one side of the equation, and the constant terms on the other side. To do this, we subtract 2x from both sides, and add 4 to both sides. We get:

$$5x = 10$$

- Finally, we need to isolate x by dividing both sides by 5. We get:

$$x = 2$$

This is the solution of the equation. You can check it by plugging it back into the original equation and simplifying. You should get a true statement.
