Question

Eight more than 2 times a number is 22. Find the number.

Answer 1

a number is 7

Explanation:

First let's set up the equation:

8 + 2x = 22 (a number is replaced by x in this equation)

Now, to get x by itself and the answer, we need to cancel out the other numbers by adding, subtracting, multiplying, or dividing to both sides. I'm going to start with the eight, because it's the one with least complications.

8-8 + 2x = 22-8

We're left with 2x = 14

Now we divide both sides by two so x is by itself.

2x/2 = 14/2

Result:

x = 7

Hope this helps!
