That word "equals" in there makes it an equation.
Well, darling, a 2-step equation that equals 21 could be something like 2x + 5 = 21. First, you'd subtract 5 from both sides to get 2x = 16, then divide by 2 to find x = 8. Voila, you've got yourself a sassy solution!
Subtract 1 form both sides of the equation

Oh, what a happy little math problem! Let's create a beautiful equation together. How about starting with 2 + 2 = 4, then we'll multiply by 2 to get 4 x 2 = 8. There you go, a lovely 4-step equation that equals 8. Just remember, there are no mistakes, only happy little accidents in math!
To form a 2 step equation that would equal 8, you start out with your variable equaling 8. X = 8 Then, add a number to both sides. We will use 4 for this example. X + 4 = 8 + 4 Now, multiply everything by any number, we will use 3 for this example. 3X + 12 = 36 Congratulations, you now own your very own 2 step equation.
3x+2 = 8
If: n3 = 8 Then: n = 2

Subtract 1 form both sides of the equation
To solve the equation 2X+8=X+10 the first step is to get all instances of the variable 'X' on the same side of the 'equals' sign. To do this, we must first subtract 'X' from both sides of the equation: 2X+8-X=X+10-X which then becomes X+8=10. The next step is to leave the variable 'X' alone on it's side of the 'equals' by subtracting the numeral 8 from both sides of the equation: X+8-8=10-8 which then becomes X=2. To confirm that the solution is correct, we then substitute the solution we arrived at into the original equation in place of the variable 'X': 2*2+8=2+10 2*2=4 so: 4+8=2+10 4+8=12 and 2+10=12 so the final solution is: 12=12 Therefore the answer to the question "Is 2X+8 equal to X+10" is Yes, and the value of the variable 'X' is 2

2 plus 8 equals 8 plus 2 demonstrates the commutative property of addition
