Transcript text: Solve the following equation using a graphical method.
\[
\frac{2 x}{3}-1=\frac{2 x-2}{2}+1
\]
Graph the left side of the equation as $y_{1}$ and the right side as $y_{2}$ on the same viewing window. Choose the correct graph below.
All graphs have viewing window $[-10,10]$ by $[-10,10]$ with Xscl $=1$ and Yscl $=1$.
Solution
Solution Steps
Step 1: Rewrite the Equation
Rewrite the given equation in a more manageable form:
\[ \frac{2x}{3} - 1 = \frac{2x - 2}{2} + 1 \]
Step 2: Simplify Both Sides
Simplify both sides of the equation:
\[ \frac{2x}{3} - 1 = x - 1 + 1 \]
\[ \frac{2x}{3} - 1 = x \]
Step 3: Graph the Equations
Graph the left side of the equation as \( y_1 = \frac{2x}{3} - 1 \) and the right side as \( y_2 = x \).
Step 4: Identify the Correct Graph
Compare the graphs of \( y_1 \) and \( y_2 \) to the given options. The correct graph will show the intersection of \( y_1 \) and \( y_2 \).
