Answer: Isolating the variable
Step-by-step explanation: For this equation, you would have to add 3 to both sides of the equal signs. For example, you add three to negative three and then also add three to the five, which would be X = 8. To check your answer, you can plug in the variable. To do this, just replace the variable(s) with the answer you got. This would be 8 - 3 = 5, which is a correct equation. Hope this helps
