4-6= -2
-6/-2 = 3
Answer:
Step-by-step explanation:
First, on the right-hand side of the equation, let's distribute the 
to each term in the parenthesis:
Now, let's move all the terms with an 
to the left-hand side, and everything else to the right-hand side of the equation:
Let's combine like terms:
Finally, let's divide each side by 
to get by itself on the left-hand side of the equation:
