Solving the Equation \( \frac{2}{3} x + 4 = 2x \)
To solve the equation \( \frac{2}{3} x + 4 = 2x \), we will follow a series of steps to isolate the variable \( x \).
Step 1: Eliminate the Fraction
To make calculations easier, we can eliminate the fraction by multiplying every term in the equation by 3, which is the denominator of the fraction:
3 \left(\frac{2}{3} x \right) + 3 \cdot 4 = 3 \cdot 2x
This simplifies to:
2x + 12 = 6x
Step 2: Rearranging the Equation
Next, we will rearrange the equation by moving all terms involving \( x \) to one side and the constant terms to the other side. We can subtract \( 2x \) from both sides:
12 = 6x - 2x
This simplifies to:
12 = 4x
Step 3: Isolating \( x \)
Now, we need to isolate \( x \) by dividing both sides of the equation by 4:
x = \frac{12}{4}
Thus, we find that:
x = 3
Conclusion
The solution to the equation \( \frac{2}{3} x + 4 = 2x \) is \( x = 3 \). You can check your work by substituting \( x \) back into the original equation to ensure both sides are equal.
