Final answer:
By subtracting 6 from both sides and then dividing by 2, we find the solution to the equation 2x + 6 = 20 is x = 7.
Step-by-step explanation:
To solve the equation 2x + 6 = 20, we need to isolate x on one side of the equation. First, we subtract 6 from both sides to get 2x = 20 - 6, which simplifies to 2x = 14. Then, we divide both sides by 2 to solve for x, giving us x = 14 / 2, which simplifies to x = 7. Therefore, the solution to the equation is x = 7.
The solution to the equation 2x + 6 = 20 can be found through a series of steps to isolate the variable x. First, subtract 6 from both sides of the equation to get 2x = 20 - 6, which simplifies to 2x = 14. Next, divide both sides of the equation by 2 to find the value of x: x = 14 / 2, which simplifies to x = 7. Therefore, the correct answer is B, x = 7.
