WebJun 14, 2024 · If a number is being subtracted from a variable, addition will be used to “undo” this operation. For example, y + 2 = 7 can be solved by subtracting 2 from both sides of the equation. y + 2 = 7 becomes y = 5. Other equations such as x − 5 = 8 can be solved using addition. When 5 is added to both sides, the equation becomes x = 13. WebIn general, we solve equations by isolating the variable; that is, we manipulate the equation to end up with the variable on one side of the "equals" sign, with a numerical value on the other side. The general process for isolation is, in a sense, undoing whatever had been done to the variable in the original equation.
