What happens to the order of operations when you’re solving a two-step equation?

• It stays the same.

• It only applies when you have to divide by a negative number.

• It reverses, so addition and subtraction come before multiplication and division.

• It doesn't matter what operation you do first because all equations are commutative.

What is the first step to solving this equation?

-5c + 6 = -4

• Subtract 6 from both sides

• multiply both sides by 5
