Today I am going to explain step by step how to solve the equation 2x-7=15. Here we go:
2x-7=15
Step 1: add 7 to both sides.
Why? You add 7 to both sides in order to get x alone. You will end up with 2x=22.
Step 2: divide by 2.
Why? Right now you have the quantity of 2x. In order to get the amount of x, you must divide by 2. This will leave you with x=11. Now you are done. Your answer is x=11.
