When you are solving a 2-step equation, you do the opposite of a 1-step equation. You do addition and subtraction first, then the multiplication second. Example: 2x + 9=16 -9 -9 2x=7 Now it's a 1-step equation 2x=7 /2 /2 Your answer would be 3.5 To check all you do is replace the variable with your answer. 2x + 9=16 2(3.5) + 9=16

It is an algebraic equation which requires 2 steps to solve it, by breaking it down in different parts, until it is easy to calculate the answer.
The first step not possible in solving an equation algebraically is not to provide an equation in the first place in which it appears to be so in this case.
Does a multi-step equation sometimes, always, or never have a solution?
