The difference of 2 times a number x and 6 is -24

Question

The difference of 2 times a number x and 6 is -24

Answer 1

Here's what we know:

The difference (subtraction)

2 times a number (we have an unknown number multiplied by 2: 2x)

and 6 (the number we're subtracting is 6: 6)

is -24 (= 24)

Put the pieces together, and we have:

2x - 6 = -24

Now we just need to isolate x. Start by adding 6 to both sides:

2x - 6 + 6 = -24 + 6

2x = -18

Now divide:

2x / 2 = -18 / 2

Solve that, and you'll have your answer.
