One simple way to solve linear equations with decimals is to get rid of the decimals completely. Here’s how you can do it:
Multiply everything: If you have an equation like (0.4x + 2 = 3.2), just multiply every part by 10. This will help you get rid of the decimals:
(4x + 20 = 32)
Change fractions: If there are fractions in your equation, try making them have the same bottom number (denominator). For example, in (x/3 + 2 = 5/2), change the fractions so you don’t have to deal with them one at a time.
Use opposite operations: Always remember to get the variable (the letter) by doing the opposite operation step by step.
Check your answers: Once you find a solution, put it back into the original equation to make sure it works.
These tips can make solving equations quicker and help you make fewer mistakes!
