Of course! I'd be happy to help you with your pre-algebra homework. Solving equations by multiplying or dividing is a fundamental concept in algebra. Let's get started!
To solve equations using multiplication or division, we aim to isolate the variable on one side of the equation. Here's the step-by-step process:
1. Start by simplifying both sides of the equation as much as possible.
2. If there are any coefficients (numbers multiplied by the variable), you want to get rid of them by dividing both sides of the equation by the coefficient.
- For example, if you have the equation 3x = 9, divide both sides by 3 to isolate the variable: 3x/3 = 9/3, which simplifies to x = 3.
3. If the variable is already isolated, proceed to the next step.
4. If the variable is divided by a coefficient, multiply both sides of the equation by that coefficient to remove the division.
- For example, if you have the equation (1/4)y = 5, multiply both sides by 4 to get rid of the fraction: (1/4)y * 4 = 5 * 4, simplifying to y = 20.
Remember, when you perform an operation (multiplication or division) on one side of an equation, you must perform the same operation on the other side to maintain equality.
If you have a specific equation you're struggling with, feel free to provide it, and I'll be glad to guide you through the steps.
