Answer:
19= 12 + 3x
Step-by-step explanation:
This kind of question can be a little confusing at times especially when the numbers get bigger and messier so let's break it down piece by piece. Nineteen is twelve more than three times a number. This means that nineteen is twelve plus three times that unknown number. Three times that unknown number can be written as three times x or just 3x. Put that all together and you get 19 = 12 + 3x.

Answer:
x = 10
Step-by-step explanation:
We need to isolate X.
3x - 7 = x + 13
subtract 13
3x - 7 - 13 = x
combine like terms
3x - 20 = x
subtract 3x
- 20 = x - 3x
Combine like terms
- 20 = - 2x
Divide by -2
10 = x
