Solving One Step Equations Solutions Examples Videos Worksheets Solving one step equations (basics) solve one step equation with addition. solve for x in the following equation: x 8 = 14 . to find the solution for this equation, we must first get x by itself on the left side. since x has 8 added to it, we must use the inverse operation of addition, subtraction. so we will subtract 8 from each side. Technically, that last example was a two step equation, because solving it required adding one thing to both sides of the equation, and then subtracting another thing to both sides. the important thing to notice is that you can add and subtract variables to the other side of an equation, just like you can add and subtract numbers to the other side.
Solving One Step Equations Solving one step addition equations. solving an equation for x means isolating the x on one side of the equation. to isolate the x, the following techniques are used. if a number is being added to x, subtract the number from both sides of the equation. if a number is being subtracted from x, add the number to both sides of the equation. The steps to solve one step equations are as follows: step 1: note down the equation. for example x − 5 = 10. an equation will have a variable (x), which denotes an unknown value, and it will also have a constant, which is a number you need to add or subtract from the variable to equal a certain sum or difference.
