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. WebA w = l. Now that you have rewritten the formula, you can input the variables and find the value of l: 20 8 = l. so including the units l = 2.5 cm. Method two: first plug in the information you have, then solve for the variable you need. Plugging in the numbers you found above into the formula A = l w, 20 = l ⋅ 8.
