Solve 12x-19=5x+9please show working​

4

Explanation:

your goal is to isolate the x. to do this, youd subtract 5x from both sides

7x-19=9

keep in mind you want to isolate the x. now you want to ADD the 19 to both sides because its a negative number. you want to get it to 0.

7x=28

now this is a one step equation. you just need to divide 28/7 and youll get 4
