Question

when solving an equation, which is the best first step to begin to simplify the equation? -2(x+3)=-10​

Answer 1

Answer: Following the rules of PEMDAS, you want to divide both sides of the equation by -2. This would change your equation to x+3=5. Then you move your constant to the right-hand side and change its sign. Your equation is now x=5-3. subtract 5-3 and your answer is x=2.
