How to Solve Simple Algebra Equations for Beginners

Solving simple algebra equations is a fundamental skill that every student should master. When faced with an equation like '3y = 27', the goal is to isolate the variable 'y' to find its value. Here's how to approach these types of problems step by step.

**Step 1: Understand the Equation**
In the equation '3y = 27', '3' is the coefficient of 'y', meaning it is multiplied by 'y'. The goal is to get 'y' by itself on one side of the equation. This is crucial because it allows us to determine the value of 'y'.

**Step 2: Isolate 'y'**
To isolate 'y', you need to perform an operation that will eliminate the coefficient. Since 'y' is currently multiplied by '3', you can do the opposite operation, which is division. Divide both sides of the equation by '3':

\[ rac{3y}{3} = rac{27}{3} \]
This simplifies to:
\[ y = 9 \]

**Step 3: Verify Your Solution**
It's always a good idea to check your work. You can substitute '9' back into the original equation to see if it holds true:
\[ 3(9) = 27 \]
Since this statement is true, 'y = 9' is indeed the correct solution.

**Real-World Applications**
Understanding how to solve simple algebra equations can be useful in various real-life situations. For example, if you're trying to budget your allowance or determine how much of something you can buy, algebra helps you make those calculations. You might also encounter algebra in science, especially when calculating measurements or analyzing data.

**Practice Problems**
Here are a few more equations to practice with:
1. '4y = 36'
2. '2y + 5 = 15'
3. '5y = 45'
Try solving these on your own, and remember to isolate 'y' by performing the necessary operations!
