How do you solve 4x + 7 = 6x - 1?

1 Answer

x=4.

Explanation:

Start by bringing all of the variables onto one side of the equation. In this case, Let's subtract 4x from both sides to give us:

7=6x-4x-1

Perform indicated steps as allowed (subtract 4x from 6x, giving us 2x). So:

7=2x-1

Let's get all of the non-variables onto one side of the equation, the simplest way to do this is to add 1 to both sides:

7+1 =2x

Perform indicated steps as allowed (add 7 plus 1, giving us 8). Now, we are looking at

8=2x

Let's divide both sides by the coefficient of x (which is 2), and that gives us:

4=x

Because the equals sign is transitive, we can also state this as

x=4
