Transcript text: Find all real solutions of the equation.
\[
\begin{array}{l}
7=\sqrt{3 x-2} \\
x=\square
\end{array}
\]
Solution
Solution Steps
To find the real solutions of the equation \( 7 = \sqrt{3x - 2} \), we need to isolate \( x \). First, square both sides of the equation to eliminate the square root. Then, solve the resulting linear equation for \( x \).
Step 1: Isolate the Square Root
Given the equation:
\[ 7 = \sqrt{3x - 2} \]
Step 2: Square Both Sides
Square both sides to eliminate the square root:
\[ 7^2 = (\sqrt{3x - 2})^2 \]
\[ 49 = 3x - 2 \]
Step 3: Solve for \( x \)
Rearrange the equation to solve for \( x \):
\[ 49 + 2 = 3x \]
\[ 51 = 3x \]
\[ x = \frac{51}{3} \]
\[ x = 17 \]
