Answer:
Step-by-step explanation:
To solve the equation \(4x - 9 = 25\), we need to isolate \(x\) on one side of the equation.
1. Add 9 to both sides of the equation:
\[ 4x - 9 + 9 = 25 + 9 \]
\[ 4x = 34 \]
2. Now, divide both sides by 4 to solve for \(x\):
\[ \frac{4x}{4} = \frac{34}{4} \]
\[ x = \frac{34}{4} \]
\[ x = 8.5 \]
Now, let's check the solution by substituting \(x = 8.5\) back into the original equation:
\[ 4(8.5) - 9 = 25 \]
\[ 34 - 9 = 25 \]
\[ 25 = 25 \]
Since the left-hand side equals the right-hand side, the solution \(x = 8.5\) is correct.
