Solve for x: 2x + 6 = 14

x = 8

x = -4

x = 4

x = 10

To solve for x in the equation 2x + 6 = 14, we can follow these steps:

1. Subtract 6 from both sides of the equation: 2x + 6 - 6 = 14 - 6
Simplifying this gives us: 2x = 8

2. Divide both sides of the equation by 2 to isolate x: (2x)/2 = 8/2
Simplifying this gives us: x = 4

So, the solution to the equation is x = 4.

John has a golf score of 140. Each time he plays, the score decreases by 4. Which of the following sequences can represent this situation?

{140, 136, 132, 128...}

{140, 144, 148, 152...}

{4, 8, 12, 16...}

{4, 0, -4, -8...}

The correct sequence that represents John's decreasing golf score of 140, where the score decreases by 4 each time, is:

{140, 136, 132, 128...}
