**Answer:**

-5=5x+5y when you divide it by 5 I don't understand how the equation then becomes x=-1-y when you are dividing by a positive 5

**Step-by-step explanation:**

Example Question #1. If 7x + y = 25 and 6x + y = 23, what is the value of x? You could also solve one equation for y and substitute that value in for y in the other equation: 6x + y = 23 → y = 23 – 6x.
