the alikes of solving a one-step or two-step equation: in solving an equation is to have only variables on one side of the equal sign and numbers on the other side of the equal sign. The other alike is to have the number in front of the variable equal to one the variable does not always have to be x. These equations can use any letter as a variable.
When you solve a one-variable equation, your goal is to isolate the variable.To isolate the variable means to make it be alone on one side of the equals sign.In the equation shown here, you can isolate the variable by subtracting 9 from both sides of the equation and simplifying
1 + 12 = 13
Well, isn't that just a happy little question! To create a two-step equation that equals 11, you can start with x + 3 = 14. First, you would subtract 3 from both sides to get x = 11. And there you have it, a lovely little equation that equals 11. Just remember, there are no mistakes, only happy little accidents in math!
One out of many examples of two step equations that equal 29 is: (9 x 3) + 2
