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.
