Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Eliminate the fraction by multiplying both sides of the equation by the reciprocal of 23\frac{2}{3}.
  • Step 2: Simplify the resulting equation.
  • Step 3: Solve for x x .

Now, let's work through each step:

Step 1: Multiply both sides of the equation by 32\frac{3}{2} to eliminate the fraction. This gives:

32×4=32×((2x1)×23)\frac{3}{2} \times 4 = \frac{3}{2} \times \left((2x - 1) \times \frac{2}{3}\right)

Simplifying, the left side becomes:

6=2x16 = 2x - 1

Step 2: Add 1 to both sides to solve for 2x 2x :

6+1=2x1+16 + 1 = 2x - 1 + 1

7=2x7 = 2x

Step 3: Divide both sides by 2 to isolate x x :

72=x\frac{7}{2} = x

Converting 72\frac{7}{2} to a decimal gives us:

x=3.5x = 3.5

Therefore, the solution to the problem is x=3.5 x = 3.5 .

Answer

3.5 3.5
