Question

Twice the difference of a number and 9 is equal to 2

Answer 1

x = 10

Explanation:

Let's break down the sentence and translate it into an equation:

"Twice the difference of a number and 9" means 2 times (x - 9), where x is the number.

"Is equal to 2" means = 2.

Putting it all together, we get:

2(x - 9) = 2

Simplifying:

2x - 18 = 2

Adding 18 to both sides:

2x = 20

Dividing by 2:

x = 10

So the solution is x = 10.
