Answer:

a) add 6 to both sides

Step-by-step explanation:

To solve the given equation the first step would be to add six to both sides. This step is the first step in isolating the variable (x) in the equation. To prove that this is correct I will show how to solve the equation and check my answer.

How to solve:

Step 1 - Add six to both sides of the equation

2x - 6 = 14

2x - 6 + 6 = 14 + 6

2x = 20

Step 2 - Divide both sides of the equation by two

2x = 20

2x/ 2 = 20/ 2

x = 10

Check my answer:

Step 1 - Insert the value of x in the equation

2x - 6 = 14

2(10) - 6 = 14

Step 2 - Multiply ten and two

2(10) - 6 = 14

20 - 6 = 14

Step 3 - Subtract six from twenty

20 - 6 = 14

14 = 14 ✓

Therefore, the first step to solve the equation 2x - 6 = 14 is a) add 6 to both sides.
