How can you solve problems involving equations that contain addition subtraction multiplication or division?
Pls help me!!
you can solve them by deciding to see what situations need to be used to solve that problem it could be any you just have to think carefully
idk
To solve problems involving equations that contain addition, subtraction, multiplication, or division, you can follow these steps:
1. Simplify the equation: Combine like terms and perform any necessary operations within parentheses or brackets.
2. Isolate the variable: Move all other terms to one side of the equation to isolate the variable on the other side.
- If there are addition or subtraction operations involving the variable, use the inverse operation to move it to the other side of the equation. For example, if you have "2x + 5 = 12," you can subtract 5 from both sides or "undo" the addition to get "2x = 7."
- If there are multiplication or division operations involving the variable, use the inverse operation to move it to the other side of the equation. For example, if you have "3x/2 = 6," you can multiply both sides by 2/3 or "undo" the division to get "x = 4."
3. Solve for the variable: Once the variable is isolated on one side of the equation, perform any remaining operations to solve for the value of the variable.
- If there are multiple variables, you may need to use simultaneous equations or substitution to solve for their values.
4. Check the solution: Substitute the value of the variable back into the original equation to ensure that it satisfies the equation.
- If the value satisfies the equation, then it is the correct solution.
- If the value does not satisfy the equation, then you may have made an error during the solving process and should recheck your work.
By following these steps, you should be able to solve problems involving equations with addition, subtraction, multiplication, or division operations. Remember to practice and review mathematical rules to improve your problem-solving skills.
