Step-by-step Solution
To solve the equation \( 10x + 5y = 120 \), we can express it in terms of one variable or find specific values for \( x \) and \( y \).
### Step 1: Simplify the equation
We can simplify the equation by dividing all terms by 5:
\[
2x + y = 24
\]
### Step 2: Solve for \( y \)
Now, we can express \( y \) in terms of \( x \):
\[
y = 24 - 2x
\]
### Step 3: Find specific values
We can choose specific values for \( x \) to find corresponding values of \( y \).
1. If \( x = 0 \):
\[
y = 24 - 2(0) = 24 \quad \Rightarrow \quad (0, 24)
\]
2. If \( x = 6 \):
\[
y = 24 - 2(6) = 12 \quad \Rightarrow \quad (6, 12)
\]
3. If \( x = 12 \):
\[
y = 24 - 2(12) = 0 \quad \Rightarrow \quad (12, 0)
\]
### Step 4: General solution
The general solution for the equation \( 10x + 5y = 120 \) can be expressed as:
\[
y = 24 - 2x
\]
This represents a line in the \( xy \)-plane, and any point \((x, y)\) that satisfies this equation is a solution.
### Conclusion
The equation \( 10x + 5y = 120 \) can be simplified to \( y = 24 - 2x \), and you can find specific solutions by substituting different values for \( x \).
Quick Answer
The equation \( 10x + 5y = 120 \) simplifies to \( y = 24 - 2x \). You can find specific solutions by substituting values for \( x \).
