Final answer:Amulti-step equationthat equals 9 is 2x + 3 = 9. By isolating x and solving for x, we find that x equals to 3. The result can be checked by substituting 'x' into the original equation to affirm it equals to 9.Explanation:A multi-step equation is analgebraicequation that requires multiple steps to solve. For example, consider the equation 2x + 3 = 9. Below is the step by step explanation on how to solve this equation to equal 9:Firstly, commence by isolating the terms with the unknown variable on one side of the equation. Here, we subtract 3 from both sides of the equation to keep the equation balanced. This results into 2x = 9 - 3.Calculate thevalueof the right side of the equation, which gives 2x = 6.Next, we want to solve for 'x'. As 'x' is currently multiplied by 2, we'll divide both sides of the equation by 2. This gives us x = 6/2.Finally, perform thedivisionto find x = 3Always remember to check the answer by substituting 'x' into the original equation to make sure it equals to 9. In this case, 2*3 + 3 does indeed equal 9, which confirms that our solution is correct.Learn more about Multi-Step Equation...
